This Privacy Policy explains how Ivywall Corporation collects, uses, stores, and protects personal data when you use CONCENTRATE.
We use data to operate the app, sync progress, process purchases, provide support, comply with legal obligations, and improve service quality.
We do not sell your personal data.
We process and store data via Supabase infrastructure. Data may be transferred to and stored in the United States. By using the app, you acknowledge and consent to this transfer, storage, and processing in the U.S.
Because there is no consistent industry standard for DNT signals, the app does not currently respond differently to browser or device DNT settings.
For authentication and session continuity, Supabase may store local tokens in app or browser storage. These are used for account access and security, not for behavioral advertising.
The app is not directed to children under 13, and we do not knowingly collect personal data from children under 13. If you believe such data was provided, contact us to request deletion.
You may request deletion through the app (when available) or by emailing me.question.contact@gmail.com. We will process verified deletion requests subject to legal retention requirements.
For privacy, legal, or billing support, contact: me.question.contact@gmail.com.

Q: Do you sell my personal data?
