Privacy Policy — Mobile Wiki

Last updated: 2026-09-13

Mobile Wiki (“the app”) is a single-user personal wiki for Android. This document describes what data the app handles and where it goes.

TL;DR

• The app has no servers and does not collect, store, or transmit any data about you to the developer.
• Everything you create lives in a local SQLite database on your device.
• The only network traffic the app generates is to the LLM provider you choose (Anthropic or Google), using your own API key, with the prompts you explicitly send by tapping “Save & process” or asking a question.

Data the app stores on your device

• Pages, source log, and metadata — in an on-device SQLite database managed by expo-sqlite. Not encrypted at rest beyond Android’s full-disk encryption.
• API keys — in expo-secure-store, which uses Android’s EncryptedSharedPreferences (backed by the Android Keystore). Never written to plaintext storage or logs.
• Theme preference — in expo-secure-store.

Uninstalling the app removes all of the above. There is no cloud backup (android.allowBackup is false).

Data sent to third parties

When you tap Save & process or ask a question, the app sends the relevant text to the LLM provider you have selected:

• Anthropic Claude — https://api.anthropic.com — governed by Anthropic’s privacy policy: https://www.anthropic.com/legal/privacy
• Google Gemini — https://generativelanguage.googleapis.com — governed by Google’s privacy policy: https://policies.google.com/privacy

You authenticate directly with that provider using your own API key. The developer of this app has no access to your prompts, responses, or account.

The app contacts no other network endpoints. There is no analytics, crash reporting, advertising SDK, or telemetry.

Data we (the developer) collect

None. There is no server-side component. We cannot see your wiki, your prompts, your API keys, or whether you’ve installed the app.

Your controls

• Switch providers at any time from Settings → Provider.
• Delete a provider’s API key from Settings.
• Export your wiki to a JSON file you control (Settings → Export).
• Wipe everything by uninstalling the app.

Children

The app is not directed at children. Use of the underlying LLM providers is governed by their respective terms, which generally require users to be at least 13 or 18 years old depending on jurisdiction.

Changes to this policy

If this policy changes, the new version will be published at https://taha-1005.github.io/mobile-wiki-privacy/privacy.html and the Last updated date above will be revised.
