Grello - Gratitude AI ("Grello", "we", "our") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.
Grello is designed to be local-first. The following data is stored only on your device and never sent to our servers:
When you use AI features (chat, affirmations, entry reflections), the text of your message is sent to our secure proxy server and forwarded to Google's Gemini API for processing. We do not store these messages on our server — they are forwarded in real-time and discarded.
We collect an anonymous device identifier (a random ID stored on your device) solely for rate-limiting API usage. This ID is not linked to your name, email, or Apple ID.
Subscription purchases are processed by Apple through the App Store. We use RevenueCat to manage subscription status. RevenueCat receives your anonymous App Store transaction data — not your name or personal details. See RevenueCat's Privacy Policy.
We do not use any third-party analytics, tracking, or advertising SDKs. We do not collect crash reports, usage analytics, or behavioural data.
Grello is not directed at children under 13. We do not knowingly collect data from children.
Since your data is stored locally, deleting the app removes all your data. If you'd like to request deletion of any server-side rate-limit records, contact us.
We may update this policy. Material changes will be communicated through the app.
