Recallleaf privacy policy

Recallleaf helps you write and organize notes, create flashcards, and request optional AI assistance. Contact us at zenith.stack.studio@gmail.com.

Your notes stay on your device

Notes, drafts, notebooks, and flashcards are saved in the app’s private local storage. We do not provide cloud note sync. Uninstalling the app or clearing its storage can remove this data. You can export a readable JSON backup or share a note using Android’s share sheet. You choose the destination; that destination’s privacy practices apply. Store backups securely.

Optional AI

When you confirm an AI request, the selected note text is sent over HTTPS to our Cloudflare backend, OpenRouter, and the model provider selected by OpenRouter. AI is optional. Do not submit confidential or sensitive information you do not want these services to process.

Our backend does not save note text or generated results as a history. We request providers that OpenRouter marks as disallowing data collection, but providers’ own processing and retention policies still apply. Free model availability can change. Read OpenRouter’s privacy policy and Cloudflare’s privacy policy.

Sessions and usage limits

The app creates a random anonymous session identifier to protect the shared free AI allowance. Its token is encrypted in Android Keystore-backed local storage. It is not a cloud account and does not sync or recover your notes. Our backend stores daily usage counts associated with that identifier and a one-way, secret-salted hash of the network address. Daily counters are cleared after the UTC day ends. Cloudflare necessarily processes network addresses and technical request information to deliver and protect the service.

Reporting AI content

If you choose “Report AI result”, we send the displayed result and your selected reason to Zenith Stack Studio through Cloudflare. Your source note is not attached separately. The result may itself contain information from the note. Reports are retained for up to 30 days for safety review. You can contact us with the report ID to request deletion earlier.

Advertising

Recallleaf integrates Google AdMob. Where applicable, a Google consent form lets you choose how advertising data is used before ads are requested. You can reopen available consent choices in Settings. Google may process device identifiers, network addresses, app interactions, and diagnostic data for advertising, fraud prevention, and measurement. See Google’s privacy policy and how Google uses data from apps. Notes are not intentionally provided to the advertising SDK.

Intended audience

The first release is intended for adults aged 18 and over, including university students. It is not directed to children.

Your choices

You can use offline features without AI, decline an AI request, export your notes, and control available advertising consent choices. Clear the app’s storage through Android settings to remove its local data, after exporting anything you want to keep. Contact the support address above about privacy or a report. This policy will be updated when the app’s data practices change.
