+# EnvelopeGenerator — Copilot Context Notes (English)
+
+## Purpose
+A digital document signing system. Senders upload PDFs and place signature annotation fields via PSPDFKit (EnvelopeGenerator.Web). Receivers open the document in a Blazor WASM viewer, confirm each signature field via a checkbox overlay, draw/type/upload their signature, and export the stamped PDF.
+
+---
+
+## Solution Structure
+
+| Project | Target | Description |
+|---|---|---|
+| `EnvelopeGenerator.API` | net8.0 | ASP.NET Core Web API. Receiver auth (cookie), annotation reading, PDF serving. |
+| `EnvelopeGenerator.ReceiverUI` | net8.0 WASM | Blazor WebAssembly. Receiver UI. YARP proxies API calls. |
+| `EnvelopeGenerator.Web` | net7/8/9 | Razor Pages. Sender UI + PSPDFKit annotation placement. |
+| `EnvelopeGenerator.Application` | multi | MediatR CQRS handlers. |
+| `EnvelopeGenerator.Domain` | multi | Domain models, constants, interfaces. |
+| `EnvelopeGenerator.Infrastructure` | multi | EF Core repos, DB context. |
+| `EnvelopeGenerator.PdfEditor` | multi | iText7 utilities. NOT used in ReceiverUI flow. |
+| `EnvelopeGenerator.DependencyInjection` | multi | DI registration helpers. |
+| VB.NET projects (Service/Form/BBTests) | net462 | Legacy. Do NOT touch. |
+
+---
+
+## Key Files
+
+| File | Purpose |
+|---|---|
+| `ReceiverUI/Pages/ReportViewer.razor` | Main receiver page. All signing logic. |
+| `ReceiverUI/wwwroot/js/receiver-signature.js` | JS: checkbox overlay, signature pad (draw/type/image). |
+| `ReceiverUI/wwwroot/fake-data/annotations.json` | Dev-mode fake annotations (YARP proxy target). |
+| `ReceiverUI/Models/AnnotationDto.cs` | Annotation position model. All properties non-nullable. |
+| `ReceiverUI/Services/AnnotationService.cs` | Fetches `List<AnnotationDto>` from API or fake-data. |
+| `ReceiverUI/Services/DocumentService.cs` | Fetches PDF bytes from API. |
+| `ReceiverUI/Services/AuthService.cs` | Manages receiver session cookie. |
+| `API/Controllers/AnnotationController.cs` | GET `api/Annotation/{key}` ? annotation list. |
+| `API/Controllers/DocumentController.cs` | GET `api/Document/{key}` ? PDF bytes. |
+
+---
+
+## AnnotationDto — Coordinate System
+
+```
+Unit   : 1/100 inch (DX units) — DevExpress XtraReports native
+Origin : Top-left corner of page
+X      : increases rightward
+Y      : increases downward
+
+A4 in DX units: Width = 827, Height = 1169
+
+Conversions:
+  PSPDFKit (pt, top-left):      xDX = xPsPdf * (100/72)
+  GDPicture (pt, bottom-left):  yDX = (pageHeightPt - yGD - elemHeightPt) * (100/72)
+  DX ? PDF points:              pt  = dx * (72/100)
+```
+
+---
+
+## ReceiverUI Signing Flow (ReportViewer.razor)
+
+### On Load (`OnInitializedAsync`)
+1. `AuthService.CheckEnvelopeAccessAsync` ? redirect to login if unauthorized
+2. `AnnotationService.GetAnnotationsAsync` ? fills `_annotations`
+3. `DocumentService.GetDocumentAsync` ? fills `_basePdfBytes` (real mode)
+4. `BuildFreshBaseReport()` ? `XtraReport` for `DxReportViewer`
+
+### Signature Popup
+- Tabs: Draw / Text / Image
+- Fields: full name (required), position (optional), place (required)
+- Saved to `_capturedSignature` record
+- If annotations exist ? popup closes ? JS checkbox overlays installed
+
+### JS Checkbox Overlay (`receiver-signature.js`)
+- `receiverSignature.installAnnotationCheckboxes(annotations, checkedIds, dotNetRef)`
+- One `.annot-sig-cb-wrapper` div per annotation, absolutely positioned over viewer scroll container
+- Position: `left = pageRect.left + ann.x * scaleX`, `top = pageRect.top + ann.y * scaleY`
+  - `scaleX = pagePixelWidth / 827`, `scaleY = pagePixelHeight / 1169`
+- Click ? `dotNetRef.invokeMethodAsync('OnAnnotationToggled', id, checked)`
+
+### Apply Signatures ("Unterschriften anwenden" — `SubmitSignaturesAsync`)
+
+**Real PDF mode (`_basePdfBytes` is set):**
+- Calls `StampSignaturesOnPdf` using **iText7** directly on PDF bytes
+- Coordinate conversion: `xPt = ann.X * (72/100)`, `yPt = pageHeight - ann.Y * (72/100) - sigHeight` (Y flip: DX top-down ? PDF bottom-up)
+- Returns stamped bytes ? loaded into new `XtraReport` with `XRPdfContent`
+- Viewer refreshed with `ViewerKey++`
+
+**Dev/fake mode (`_basePdfBytes` is null):**
+- Falls back to `AddSignatureAtAnnotation` (XtraReports DetailBand + BeforePrint counter)
+- This is intentionally left as a dev fallback only
+
+### Export
+- `reportViewer.ExportToAsync(ExportFormat.Pdf)`
+
+---
+
+## StampSignaturesOnPdf — iText7 Implementation
+
+```csharp
+// Located in ReportViewer.razor @code section
+// Called by SubmitSignaturesAsync when _basePdfBytes is available
+
+static byte[] StampSignaturesOnPdf(
+    byte[] sourcePdfBytes, byte[] signatureImageBytes,
+    string signerFullName, string signerPosition, string signaturePlace,
+    IReadOnlyList<AnnotationDto> annotations)
+{
+    // Opens PDF with PdfReader/PdfWriter
+    // For each annotation:
+    //   pageNum = ann.Page (clamped to totalPages)
+    //   xPt = ann.X * (72f/100f)
+    //   imgBottomY = pageHeight - ann.Y * (72f/100f) - sigHeightPt  ? Y-axis flip
+    //   PdfCanvas.AddImageFittedIntoRectangle(imageData, rect, false)
+    //   Separator line at bottom of image
+    //   Canvas text block below separator (font: Helvetica 7pt, color: RGB(73,80,87))
+    // Returns stamped byte[]
+}
+```
+
+---
+
+## BuildFreshBaseReport()
+
+```csharp
+// Real PDF mode:
+var report = new XtraReport();
+var detail = new DetailBand();
+report.Bands.Add(detail);
+detail.Controls.Add(new XRPdfContent { Source = _basePdfBytes, GenerateOwnPages = true });
+return report;
+
+// Dev/fake mode: returns pre-built report from ReportStorage
+```

+## NuGet Packages in ReceiverUI
+
+| Package | Version | Purpose |
+|---|---|---|
+| `DevExpress.Blazor.Reporting.Viewer` | 25.2.3 | DxReportViewer component |
+| `DevExpress.Blazor.PdfViewer` | 25.2.3 | PDF viewer |
+| `DevExpress.Drawing.Skia` | 25.2.3 | Drawing backend |
+| `itext` | 8.0.5 | PDF stamping (iText7) |
+| `SkiaSharp.*` | 3.119.1 | WASM native rendering |
+
+---
+
+## Mistakes History — Do NOT Repeat
+
+| Mistake | Why Wrong |
+|---|---|
+| `BottomMarginBand` for per-page signatures | Repeats on every page; Y offset wrong |
+| `imageY = (page-1) * 1169 + ann.Y` | Inflates DetailBand; 35 pages ? 140 pages |
+| `e.Graph?.PrintingSystem` in BeforePrint | `Graph` not on `CancelEventArgs` |
+| `ctrl.Report?.PrintingSystem` | `PrintingSystem` not on `XtraReportBase` in WASM |
+| Adding stamp endpoint to `DocumentController` | Not needed; stamping is done client-side in ReceiverUI |
+| iText7 via API (server-side) | Unnecessary; iText7 runs fine in WASM directly |
+
+---
+
+## DevExpress Article (2023-08-28) — Why It Does NOT Apply
+
+The article describes **X.509 cryptographic digital signatures** via `PdfDocumentSigner` + `Pkcs7Signer`.  
+Our use case is **visual/image stamping** at specific page coordinates — different problem, different API.  
+`XRPdfSignature` in the article requires pre-placed fields in the report designer, not runtime coordinates.
+
+---
+
+## Change Log
+
+| Session | Date | Change |
+|---|---|---|
+| 1–3 | — | Core infrastructure: services, YARP proxy, JS overlay, signature pad |
+| 4 | — | `AddSignatureAtAnnotation` with BottomMarginBand — ? repeated on all pages |
+| 5 | — | `BeforePrint` + `e.Graph?.PrintingSystem` — ? compile error |
+| 6 | — | BeforePrint counter — ? correct pattern, wrong band |
+| 7 | — | Switched to DetailBand — ? correct band |
+| 8 | — | `(page-1)*1169+Y` offset — ? 35?140 page inflation |
+| 9 | — | Fixed: `BoundsF.Y = ann.Y` + counter; created COPILOT_CONTEXT.md |
+| 10 | — | Investigated DevExpress article — not applicable to our case |
+| 10 | — | Added iText7 to ReceiverUI; implemented `StampSignaturesOnPdf` — ? deterministic coordinates, no page count side effects |
+| 10 | — | Split COPILOT_CONTEXT.md into COPILOT_CONTEXT_EN.md and COPILOT_CONTEXT_TR.md |

+
+A4 boyutlar? DX units cinsinden: Geni?lik = 827, Yükseklik = 1169
+
+Dönü?ümler:
+  PSPDFKit (pt, sol-üst):      xDX = xPsPdf * (100/72)
+  GDPicture (pt, sol-alt):     yDX = (pageHeightPt - yGD - elemHeightPt) * (100/72)

+  PDF Y ekseni çevirme:        imgBottomY = sayfaYüksekli?iPt - ann.Y*(72/100) - elemanYüksekli?iPt
+```
+

+
+## ReceiverUI ?mzalama Ak??? (ReportViewer.razor)
+
+### Sayfa Yüklenince (`OnInitializedAsync`)
+1. `AuthService.CheckEnvelopeAccessAsync` ? yetkisizse login sayfas?na yönlendir
+2. `AnnotationService.GetAnnotationsAsync` ? `_annotations` listesi dolar
+3. `DocumentService.GetDocumentAsync` ? `_basePdfBytes` dolar (gerçek mod)
+4. `BuildFreshBaseReport()` ? `XtraReport` olu?turulur, `DxReportViewer`'a verilir
+
+### `BuildFreshBaseReport()` Mant???
+```
+_basePdfBytes dolu ? XtraReport + DetailBand + XRPdfContent { GenerateOwnPages = true }
+_basePdfBytes bo? (ForceToUseFakeDocument=true) ? ReportStorage'dan LargeDatasetReport ?ablonu (XtraReport, designer'dan geldi?i gibi)
+```
+
+> NOT: `_basePdfBytes` dal? korunur (gerçek PDF modu). Dev ve test sunucusunda `PredefinedReport` (LargeDatasetReport) `XtraReport` olarak do?rudan kullan?l?r — PDF'e export ED?LMEZ.
+
+### ?mza Popup'? ("Unterschrift erstellen")
+- Sekmeler: Çizim / Yaz? / Resim
+- Alanlar: Ad soyad (zorunlu), pozisyon (opsiyonel), yer (zorunlu)
+- `_capturedSignature` record'una kaydedilir
+- Annotation varsa popup kapan?r ? JS checkbox overlay kurulur
+
+### JS Checkbox Overlay (`receiver-signature.js`)
+- `receiverSignature.installAnnotationCheckboxes(annotations, checkedIds, dotNetRef)` C#'tan ça?r?l?r
+- Her annotation için `.annot-sig-cb-wrapper` div'i, viewer scroll container'?na absolute olarak yerle?tirilir
+- **Koordinat hesab?:** `left = pageRect.left + ann.x * scaleX`, `top = pageRect.top + ann.y * scaleY`
+  - `scaleX = sayfaPixelGeni?li?i / 827`, `scaleY = sayfaPixelYüksekli?i / 1169`
+  - Bu koordinatlar sayfa-relatif ve do?ru çal???yor
+- T?klan?nca `dotNetRef.invokeMethodAsync('OnAnnotationToggled', id, checked)` ça?r?l?r
+
+### ?mza Uygulama ("Unterschriften anwenden" — `SubmitSignaturesAsync`)
+
+**Tek ortak yol (her iki mod):**
+- `SubmitSignaturesAsync` ? `BuildFreshBaseReport()` + `WireAnnotationSignatures(report, _capturedSignature)`
+- `WireAnnotationSignatures` ? `report.AfterPrint` olay?na abone olur
+- Belge olu?unca `report.PrintingSystem.Pages` dolu olur; her annotation için `Pages[ann.Page-1]` sayfas?na:
+  - `ImageBrick { Image = imza görseli, Rect = (ann.X, ann.Y, 230, 70), SizeMode = ZoomImage }`
+  - `TextBrick  { Text = bilgi metni, Rect = (ann.X, ann.Y+75, 230, 65) }`
+  - `Page.AddBrick(brick)` ile bas?l?r
+- Brick `Rect`'leri annotation `X`/`Y` (1/100 inch) ? checkbox overlay ile birebir ayn? koordinat, do?ru sayfa+konum
+- `ViewerKey++` ile viewer yenilenir
+
+**Gerçek PDF modu (`_basePdfBytes` dolu):** Yukar?daki ile ayn?; rapor `XRPdfContent`'ten olu?ur, brick'ler yine `AfterPrint` ile `PrintingSystem.Pages` üzerine bas?l?r.

+
+## GÖREV 1: ?mza Konum Hatas? (BUG) — ÇÖZÜLDÜ
+
+### Kullan?c?n?n ?ste?i
+Annotation'lardan okunan sayfa ve X/Y koordinatlar?na göre, t?pk? checkbox overlay'ler gibi, imzalar do?ru sayfa ve konumda görünsün. `_basePdfBytes` dal? korunsun; dev/test'te designer ile olu?turulan `PredefinedReport` `XtraReport` olarak do?rudan kullan?lmaya devam etsin (PDF'e export yok).
+
+### ÇÖZÜM (Oturum 12) ?
+`WireAnnotationSignatures` metodu, `report.AfterPrint` olay?nda `report.PrintingSystem.Pages[ann.Page-1].AddBrick(...)` ça??rarak imza görselini (`ImageBrick`) ve bilgi metnini (`TextBrick`) do?rudan hedef sayfaya, annotation `X`/`Y` (1/100 inch) konumunda basar.
+
+**Neden çal???r:**
+- `AfterPrint`, belge tamamen olu?tuktan sonra tetiklenir; `PrintingSystem.Pages` art?k gerçek/nihai sayfalar? içerir.
+- Sayfa indeksleme (`Pages[ann.Page-1]`) band veya veri-sat?r? tekrar?ndan **ba??ms?zd?r** ? `LargeDatasetReport`'un veri-ba?l? `detailBand1` sorununu tamamen atlar.
+- Brick `Rect` koordinatlar? raporun yerel 1/100 inch sistemindedir ? checkbox overlay ile birebir ayn?, do?ru konum.
+- Yeni sayfa eklenmedi?i için sayfa say?s? katlanmaz (35 sayfa ? 35 sayfa).
+
+**Derleme s?ras?nda ö?renilen API gerçekleri:**
+- `PrintOnPage` olay? `e.Page` VERMEZ (yaln?zca `PageIndex`/`PageCount`) ? brick eklenemez. Do?ru olay `AfterPrint` + `PrintingSystem.Pages`.
+- `Page` tipinde `InsertBrick` YOK; do?ru metot `Page.AddBrick(brick)` (brick'in `Rect`'i konumu belirler).
+- `ImageBrick.BorderStyle` tipi `BrickBorderStyle`'dir (`BorderDashStyle` de?il). Border için `Sides` + `BorderColor` kullan?ld?.
+
+### Denenen Eski Çözümler (ba?ar?s?z — referans)
+
+| Deneme | Yakla??m | Sonuç | Ba?ar?s?zl?k Sebebi |
+|---|---|---|---|
+| 1 | `BottomMarginBand` + `XRPictureBox`/`XRLabel` | Her sayfan?n alt?na ç?kt? | Band her sayfada tekrarlan?r, sayfa filtresi yok |
+| 2 | `BeforePrint` + `e.Graph?.PrintingSystem` | Derleme hatas? | `CancelEventArgs`'ta `Graph` yok |
+| 3–6 | `DetailBand` + `BeforePrint` counter | Yanl?? sayfa/konum | ?ablonun `detailBand1`'i veri sat?r? ba??na tetiklenir, sayfa ba??na de?il |
+| 7 | iText7 export/reload döngüsü | 35 ? 70 sayfa | Margin uyu?mazl???, `GenerateOwnPages` sayfalar? böldü |
+| 8 | Fake modda `BottomMarginBand` fallback | Her sayfan?n alt?nda | Koordinat yanl?? |
+
+---
+
+## YAPILMAMASI GEREKENLER
+
+| Hata | Neden Yanl?? |
+|---|---|
+| `BottomMarginBand`/`DetailBand` ile sayfa-spesifik imza | Band veri-sat?r?/sayfa ba??na tekrarlan?r, koordinat kayar |
+| `BeforePrint` counter ile sayfa filtresi | Veri-ba?l? raporda sat?r ba??na tetiklenir, güvenilmez |
+| `PrintOnPage` ile brick ekleme | `e.Page` yok; brick eklenemez |
+| `Page.InsertBrick(...)` | Yok; do?ru metot `Page.AddBrick(...)` |
+| iText7 export+reload döngüsü | Margin uyu?mazl???ndan sayfa say?s? katlan?r |
+| ?ablonu PDF'e export edip `XRPdfContent`'e yükleme | ?stenmiyor; designer raporu do?rudan kullan?lmal? |
+| Stamplama için API endpoint ekleme | Gereksiz; brick'ler client'ta bas?l?r |
+

+
+## BEKLEYEN D??ER GÖREVLER (Sonraki Chat'te Yap?lacak)
+
+### 2. ?mza Arka Plan? Özelli?i
+?mza görselinin ve bilgilerinin kaplad??? alan kadar, yar? saydam hafif gri opak dikdörtgen arka plan ekle. Böylece imza ve bilgiler arka plandaki metinlerden etkilenmez ve okunur kal?r. (Art?k brick tabanl?: `ImageBrick`/`TextBrick`'in arkas?na bir arka plan `Brick` dikdörtgeni eklenebilir.)
+
+### 3. Checkbox Renk ve Stil ?yile?tirmesi
+Mevcut checkbox'lar?n rengi ve kenarl?klar? çok dikkat çekici. Koyu füme tonlar?nda, desenli, sade ve profesyonel görünümlü bir stil olsun. (`receiver-signature.js` ve ilgili CSS.)
+
+### 4. Sayfa Aç?l???nda Otomatik ?mza Popup'?
+Sayfa aç?l?r aç?lmaz imza popup'? ç?ks?n. "Kay?tl? hiç bir imzan?z yok, tan?mlay?n?z" mesaj? gösterilsin. Kullan?c? imzas?n? tan?mlamadan ilerleyemesin. Mevcut "Unterschrift erstellen" butonu "?mzay? de?i?tir" olarak güncellensin.
+
+### 5. Otomatik ?mza Uygulama
+Kullan?c? tüm checkbox'lar? onaylad??? anda imzalar otomatik olarak uygulanmaya ba?las?n (butona t?klamaya gerek kalmas?n). Sayfan?n üstünde imza say?s? ve imzalanmas? gereken sayfalar hakk?nda bilgi gösterilsin.
+
+### 6. Checkbox - DevExpress Toolbar Pozisyon Uyumsuzlu?u (BUG)
+- Checkbox'lar browser'?n boyut/konumuna neredeyse anl?k tepki veriyor
+- DevExpress toolbar de?i?ikliklerine geç tepki gösteriyor
+- Zoom de?i?ince bazen 2-3 PDF yan yana gelebiliyor; checkbox o konumda do?ru görünüyor ama iki PDF'in yan yana gelmesi kald?r?lmal?
+- `DocumentViewer.razor`'daki `DxDocumentViewer` + `DxDocumentViewerTabPanelSettings` bile?enleri daha uygun olabilir mi? De?erlendirmesi yap?lacak.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+[Open Iconic v1.1.1](https://github.com/iconic/open-iconic)
+===========
+
+### Open Iconic is the open source sibling of [Iconic](https://github.com/iconic/open-iconic). It is a hyper-legible collection of 223 icons with a tiny footprint—ready to use with Bootstrap and Foundation. [View the collection](https://github.com/iconic/open-iconic)
+
+
+
+## What's in Open Iconic?
+
+* 223 icons designed to be legible down to 8 pixels
+* Super-light SVG files - 61.8 for the entire set 
+* SVG sprite—the modern replacement for icon fonts
+* Webfont (EOT, OTF, SVG, TTF, WOFF), PNG and WebP formats
+* Webfont stylesheets (including versions for Bootstrap and Foundation) in CSS, LESS, SCSS and Stylus formats
+* PNG and WebP raster images in 8px, 16px, 24px, 32px, 48px and 64px.
+
+
+## Getting Started
+
+#### For code samples and everything else you need to get started with Open Iconic, check out our [Icons](https://github.com/iconic/open-iconic) and [Reference](https://github.com/iconic/open-iconic) sections.
+
+### General Usage
+
+#### Using Open Iconic's SVGs
+
+We like SVGs and we think they're the way to display icons on the web. Since Open Iconic are just basic SVGs, we suggest you display them like you would any other image (don't forget the `alt` attribute).
+
+```
+<img src="/open-iconic/svg/icon-name.svg" alt="icon name">
+```
+
+#### Using Open Iconic's SVG Sprite
+
+Open Iconic also comes in a SVG sprite which allows you to display all the icons in the set with a single request. It's like an icon font, without being a hack.
+
+Adding an icon from an SVG sprite is a little different than what you're used to, but it's still a piece of cake. *Tip: To make your icons easily style able, we suggest adding a general class to the* `<svg>` *tag and a unique class name for each different icon in the* `<use>` *tag.*  
+
+```
+<svg class="icon">
+  <use xlink:href="open-iconic.svg#account-login" class="icon-account-login"></use>
+</svg>
+```
+
+Sizing icons only needs basic CSS. All the icons are in a square format, so just set the `<svg>` tag with equal width and height dimensions.
+
+```
+.icon {
+  width: 16px;
+  height: 16px;
+}
+```
+
+Coloring icons is even easier. All you need to do is set the `fill` rule on the `<use>` tag.
+
+```
+.icon-account-login {
+  fill: #f00;
+}
+```
+
+To learn more about SVG Sprites, read [Chris Coyier's guide](http://css-tricks.com/svg-sprites-use-better-icon-fonts/).
+
+#### Using Open Iconic's Icon Font...
+
+
+##### …with Bootstrap
+
+You can find our Bootstrap stylesheets in `font/css/open-iconic-bootstrap.{css, less, scss, styl}`
+
+
+```
+<link href="/open-iconic/font/css/open-iconic-bootstrap.css" rel="stylesheet">
+```
+
+
+```
+<span class="oi oi-icon-name" title="icon name" aria-hidden="true"></span>
+```
+
+##### …with Foundation
+
+You can find our Foundation stylesheets in `font/css/open-iconic-foundation.{css, less, scss, styl}`
+
+```
+<link href="/open-iconic/font/css/open-iconic-foundation.css" rel="stylesheet">
+```
+
+
+```
+<span class="fi-icon-name" title="icon name" aria-hidden="true"></span>
+```
+
+##### …on its own
+
+You can find our default stylesheets in `font/css/open-iconic.{css, less, scss, styl}`
+
+```
+<link href="/open-iconic/font/css/open-iconic.css" rel="stylesheet">
+```
+
+```
+<span class="oi" data-glyph="icon-name" title="icon name" aria-hidden="true"></span>
+```

+        <h2>1. Allgemeine Informationen</h2>
+        <p>In der heutigen schnelllebigen und zunehmend digitalen Welt, sind personenbezogene Daten eine wichtige
+            Ressource. Ihre Daten sind wertvoll und müssen daher mit der durch diverse Gesetze und Vorschriften (DSGVO,
+            TDDDG, ...) gebotenen Sorgfalt behandelt werden.</p>
+        <p>Als Anbieter von lokalen Lösungen (OnPremise) setzt der Hersteller des signFLOWs, die Digital Data GmbH,
+            einen klaren Schwerpunkt auf Datenschutz und Datensicherheit. Für Sie bedeutet dies, dass nur die nötigsten
+            Daten erhoben und gespeichert werden (Datensparsamkeit bzw. Datenminimierung). Außerdem kommen bei der
+            Verarbeitung aktuelle und als sicher geltende Technologien zum Einsatz.</p>

+        <h2>3. Datenerhebung</h2>
+        <h3>3.1 Die folgenden Kategorien personenbezogener Daten werden verarbeitet</h3>
+        <ul>
+            <li>Namen: Benutzername, Vor- und Zunamen sowie Ihre digitale Unterschrift</li>
+            <li>Kontaktdaten: Telefonnummer, Mobilfunknummer und E-Mail-Adresse</li>
+            <li>Technische Daten: IP-Adresse, Zeitpunkt des Zugriffs oder Zugriffsversuchs</li>
+        </ul>
+
+        <h3>3.2 Ursprung der personenbezogenen Daten</h3>
+        <p>Sie haben die unter 3.1 stehenden Daten vorab an Ihren Geschäftspartner (die verantwortliche Stelle)
+            übermittelt. Diese Übermittlung kann mündlich per Telefon, im persönlichen Kontakt, per E-Mail oder per
+            Kontaktformular geschehen sein.</p>
+        <p>Ihre digitale Signatur übermitteln Sie eigenständig, bei der Unterzeichnung eines Dokuments.</p>
+
+        <h3>3.3 Aufbewahrungsfristen / Speicherungsdauer</h3>
+        <ul>
+            <li>Die automatische E-Mail Korrespondenz wird für 6 Jahre aufbewahrt.</li>
+            <li>Unterzeichnete Verträge werden für die Dauer ihrer Laufzeit + 10 Jahre aufbewahrt.</li>
+            <li>Der technische Vorgang wird in der signFLOW Softwarelösung je nach Dokumentart bzw. Vertragsart
+                unbegrenzt aufbewahrt.</li>
+        </ul>
+        <p>Ihre personenbezogenen Daten werden aber grundsätzlich anonymisiert, wenn:</p>
+        <ul>
+            <li>Der Vertrag ausgelaufen ist und die gesetzliche Aufbewahrungszeit vorbei ist.</li>
+            <li>Der Vertrag von Ihnen abgelehnt wurde bzw. nie unterschrieben wurde.</li>
+        </ul>
+        <p>Die gesetzlichen Grundlagen dieser Aufbewahrungsfristen bieten unter anderen:</p>
+        <ul>
+            <li>Handelsgesetzbuch (HGB)</li>
+            <li>Abgabenordnung (AO)</li>
+            <li>Grundsätze zur ordnungsgemäßen Führung und Aufbewahrung von Büchern, Aufzeichnungen und Unterlagen in
+                elektronischer Form sowie zum Datenzugriff (GoBD)</li>
+        </ul>
+        <p>
+            Abhängig von der spezifischen Dokumentart, kann die Aufbewahrungsfrist variieren. Außerdem können sich
+            Zeiten
+            verlängern, falls Unregelmäßigkeiten auftreten. Z.B.: eine rechtliche Auseinandersetzung droht oder aktuell
+            läuft.
+        </p>
+
+        <h3>3.4 Verarbeitungszweck</h3>
+        <p>Die unter 3.1 definierten personenbezogenen Daten werden verarbeitet um:</p>
+        <ul>
+            <li>Den technisch notwendigen Prozess abzubilden bzw. anbieten zu können.</li>
+            <li>Damit Sie als Endbenutzer in der Lage sind, ein zu unterzeichnendes Dokument, digital zu unterschreiben,
+                ist die Feststellung der Identität des Antragstellers, Antragsprüfung und -abwicklung, Abrechnung sowie
+                die Wahrung der Dokumentationspflichten notwendig.</li>
+        </ul>
+        <p>In Einzelfällen werden Daten zur Fehlerbehebung insbesondere bei Supportanfragen von der IT-Abteilung
+            gesondert behandelt oder ggf. an den Hersteller weitergegeben.</p>
+        <p>Im Zuge der Maßnahmen zur Sicherstellung der Informationssicherheit, insbesondere zur Identifizierung und
+            Abwehr von Angriffen, sowie zur Durchführung interner und externer Audits, der Exportkontrolle und der
+            Prüfung von Sanktionslisten, erfolgt ebenfalls eine Datenverarbeitung. Bei Anfragen gemäß §8 Abs. 2 VDG
+            werden die entsprechenden Informationen an die zuständigen Stellen übermittelt.</p>
+
+        <h3>3.5 Rechtmäßigkeit der Verarbeitung</h3>
+        <p>Ihre Daten werden auf Grundlage einer sich anbahnenden oder bereits vorhandenen Geschäftsbeziehung erhoben.
+        </p>
+        <p>Die rechtliche Grundlage für die Übermittlung an zuständige Stellen bildet §8 Abs. 2 VDG. Anfragen von
+            Betroffenen werden gemäß den Artikeln 12 bis 23 der DSGVO sowie den Paragraphen 32 bis 37 des BDSG
+            bearbeitet.</p>
+
+        <h3>3.6 Berechtigte Interessen</h3>
+        <p>Ein berechtigtes Interesse der verantwortlichen Stelle gemäß Art. 6 Abs. 1 lit. f DSGVO besteht in den
+            folgenden Fällen:</p>
+        <p>Es werden Maßnahmen zur Informationssicherheit ergriffen, die sowohl präventive technische als auch
+            organisatorische Maßnahmen sowie die Behandlung von Vorfällen umfassen. Ziel ist es, potenzielle Schäden für
+            das Unternehmen, die von der Datenverarbeitung betroffenen Personen und die Nutzer der Vertrauensdienste zu
+            bewerten und zu vermeiden.</p>
+
+        <h3>3.7 Erforderlichkeit der Daten</h3>
+        <p>Die erhobenen Daten stellen das Minimum der nötigen Daten zwecks digitaler Unterschrift dar. Ohne die unter
+            3.1 genannten Daten, kann der Dienst nicht betrieben werden.</p>
+        <p>Besonders wichtig ist die Angabe einer Mobilfunknummer oder einer deutschen Festnetznummer, da diese für die
+            Authentifizierung und die Signaturauslösung als zweiter Faktor verwendet wird. Ohne diesen
+            Sicherheitsmechanismus kann der Dienst leider nicht bereitgestellt werden.</p>
+
+        <h3>3.8 Weitergabe von Daten</h3>
+        <p>Eine systemische Übermittlung von Daten findet nicht statt.</p>
+        <p>Daten werden nur in Ausnahmefällen, zwecks Supportleistungen, an den Hersteller weitergegeben. Mit der
+            Hersteller besteht ein gültiger Auftragsdatenverarbeitungsvertrag (AVV), welcher die Sicherheit und
+            Integrität des Umgangs mit Ihren Daten gewährleistet.</p>
