Summary: Marka collects no data. There are no accounts, no server, no analytics, no ads and no tracking. Your notes are .md files that live on your device or in your own iCloud Drive.
1. Data controller
Adrián Fernández López, independent developer. Contact: adrianfernandez85@gmail.com.
2. Data we collect
Marka collects no data. The developer does not receive your notes, your files or any information about how you use the app. Marka has no server of its own and there is no account with the developer.
3. Where your notes live
- Every note is a regular .md file in a folder you choose on your device or in iCloud Drive.
- If you choose iCloud Drive, the files are stored and synced through your own iCloud, tied to your Apple ID. Apple operates iCloud under its own privacy policy and terms. The developer has no access.
- App settings (theme, editing mode, etc.) are stored in your device's local preferences.
4. Optional features and permissions
Marka asks for a permission only when you use the feature that needs it. All of them are optional: you can deny them and keep using the app.
- Microphone: to record audio notes, which are saved as attachments inside your vault, and for speech dictation. Dictation uses Apple's Speech framework, which may process the audio on Apple's servers under Apple's terms. The developer does not receive the audio.
- Photo library (iOS): to insert images into a note. The images you pick are copied into your vault's attachments folder.
- Face ID / Touch ID (iOS and iPadOS): to unlock protected notes. Biometric data never leaves your device's Secure Enclave and the app never accesses it; it only receives the system's answer on whether authentication succeeded.
5. Note locking and encryption
- The password lock is optional. The password itself is not stored: only a salted SHA-256 hash is kept in the app's local preferences.
- Optional note encryption (AES-GCM) is performed on your device. Because there is no server, the developer cannot recover a forgotten password.
6. Diagram and math previews
Diagram previews (Mermaid, Graphviz) and math previews (KaTeX) load their JavaScript libraries from a public CDN (jsDelivr) only when you open a preview. This means the CDN receives a standard web request, with the usual technical data such as your IP address. No note content is sent.
7. Share extension
On iPhone and iPad, the share extension saves text or links you share from other apps into your vault. It writes directly to your folder or your iCloud Drive; nothing goes through a server run by the developer.
8. Analytics, ads and tracking
Marka contains no ads, analytics, trackers or third-party SDKs. The app's intelligence features (summaries, keywords, related notes) are computed on your device.
9. Your rights (GDPR)
- Access and portability: your notes are .md files you already hold.
- Erasure: delete notes from the app or from Files/Finder, or uninstall the app; iCloud data is managed from the iCloud storage settings of your Apple ID.
