Springback – Habit Tracker

Last updated: September 22, 2026

Overview

Springback (“we”, “our”, or “the app”) is a habit tracker with no account and no sign-up. This policy explains what stays on your phone and the little that leaves it.

Information We Collect

We do not collect personal data. There is no sign-up, no email and no login.

Everything you enter stays on your device:

We never have access to your habits, your history or your notes.

Anonymous Usage Statistics

We use PostHog, hosted in the European Union, to count how the app is used in aggregate. This tells us whether people get through the first habit, whether they come back, and whether the upgrade screen appears at a sensible moment.

What is sent:

What is NOT sent:

You can turn usage statistics off at any time in Settings → Anonymous usage stats. When it is off nothing is sent. Because no identifier is stored, there is nothing on your phone to delete. Learn more at posthog.com/privacy.

Where Your Data Is Stored

Notifications

Third Parties

Identifiers

One identifier leaves the device: the anonymous app user ID RevenueCat assigns to the install so a purchase can be recognised. It is not tied to your name, email or hardware. Usage statistics carry no stored identifier at all.

Data Deletion

Children’s Privacy

Springback is not directed at children under 13. We do not knowingly collect data from anyone.

Changes to This Policy

If what the app sends ever changes, this page will say exactly what, before the app version that does it is released. The “Last updated” date at the top will change.
