Privacy Policy

Your privacy matters

Mentulis is designed so that your most sensitive information never has to leave your phone. This policy explains, in plain language, what we collect and how it is used.

Effective date: June 12, 2026 · Applies to the Mentulis mobile app and www.mentulis.com

What stays on your device

Your mood check-ins, journal entries, CBT exercises and self-check results are saved only on your device. We do not upload them to a server, and we cannot read them.

Your account

When you create an account, we store your email address and — if you choose to add them — your name, country of origin and province. This information is kept securely in Google Firebase and is used only to sign you in and personalise the app.

AI Companion chats

When you message the AI Companion, your conversation is sent securely to our server and to Anthropic (the company that provides the AI) to generate a reply. We do not save your conversations — they are not stored in any database, and they disappear when you leave the chat screen. Anthropic does not use your messages to train its AI.

Optional backup to your Google Drive

You can choose to back up your wellness data to your own Google Drive from the Profile tab. The backup is stored in a private app folder of your Drive — Mentulis has no access to your files and never stores a copy. Backups only happen when you tap the button.

What we share

We never sell your data. Apart from AI chat messages (described above), your data leaves your device only when you choose to — for example, when you back it up to your own Google Drive or create a PDF to share with your therapist.

This website

www.mentulis.com does not use cookies, analytics or advertising trackers. We don't collect anything about your visit.

Your choices

You are in control. You can delete all wellness data saved on your device at any time from Profile → Delete my data. This action is permanent. To delete your account and profile information, contact us at privacy@mentulis.com.

Not a medical service

Mentulis offers self-help tools and is not a substitute for professional diagnosis or treatment. In an emergency, call 911. In Canada you can also call or text 9-8-8 (Suicide Crisis Helpline, free, 24/7).
