GratiFlow

Privacy Policy

Last updated: August 28, 2026

GratiFlow helps people practice gratitude together in small, private circles. This policy explains what we collect, why, and your choices. We keep it short and plain.

What we collect

We do not collect your precise location, your contacts, advertising identifiers, or analytics about how you use the app. Ebook website measurement does not use fingerprinting, does not store your IP address in our experiment database, and does not track you across other companies' apps or websites. Face ID / biometric unlock is handled by your device and never leaves it.

How we use it

We do not sell your data, and we do not use it to track you across other companies' apps or websites for advertising.

Who processes it

We use Supabase (authentication, database, media storage) and Expo (push notification delivery) to run GratiFlow, Cloudflare to serve our website and assign an ebook landing version, Stripe to process ebook payments, and Loops to send the private download link. A language model provider may receive aggregated experiment history without visitor identifiers to propose a bounded landing candidate. These providers act on our behalf. We don't share your data with advertisers or data brokers.

Website experiments and retention

When an ebook landing experiment is active, a first-party cookie keeps the assigned version consistent for up to 35 days. Raw pseudonymous interaction events are kept for 13 months, then deleted. Aggregate decisions and their audit history may be kept longer so we do not repeat unsafe or ineffective tests. Purchase records are kept as needed for delivery, support, fraud prevention, accounting, and legal obligations.

Your browser's Do Not Track setting is respected for ebook experiment measurement. You can also opt out on this browser: .

Your circles are private

GratiFlow has no public feed. Your gratitude is visible only to the members of the private circles you join or create.

Your choices

Children

GratiFlow is not directed to children under 13, and we do not knowingly collect data from them.

Changes

We may update this policy; we'll revise the date above and, for material changes, notify you in the app.
