Effective Date: February 5, 2026
Sphyro is built on Zero-Knowledge principles. We believe your private life is your data, and we should have no technical ability to read it. The system is designed to minimize data transmission to external networks.
All your notes, financial transactions, goals, and dialogue history are stored exclusively in your Android device's internal memory (SQLite). We do not create server-side copies of your database.
For intelligent features (semantic search, context analysis) to function, your device transmits to the cloud only those data fragments necessary to answer a specific query. The cloud operates in Stateless mode: it does not store your knowledge base permanently. Your "memory" is provided to the server by your device fresh for each request and is wiped from the server's RAM immediately after the response is generated.
Sphyro does not use email addresses, phone numbers, or social networks for login. Your identity in the system is an anonymous UUID (unique identifier) tied to your device. If you delete the app, we cannot recover your data, as we have no access to your key.
Access to the local database is protected by the system's MasterKeyStore. Database files are encrypted with a key that opens only upon successful passing of a system check (PIN code, fingerprint, or Face ID).
We do not collect telemetry about your movements or interests. Technical server logs contain only anonymous information about load and system errors, not tied to the meaning of your requests.
Data is stored on your device as long as the Sphyro app is installed. When you delete the app, Android system mechanisms automatically wipe the encrypted database.
You have full control over your data. You can edit or delete any record in the "Memory" section at any time. Total data deletion is achieved by uninstalling the application from your device.
We may update this policy. In case of significant changes, information about this will appear in the app interface.
If you have any questions about this policy or the security of your data, you can contact us at: support@sphyro.me
