This policy describes what Comeback ("the app") does and does not do with information related to you. It is written to be read, not skimmed past — if anything here is unclear, that's a bug in the writing, not in the app.
Comeback stores your sessions, your Gap Log entries, and everything you write on your device only. There is no account. If you never turn on the optional "Help improve Comeback" setting, nothing about your use of this app ever leaves your phone.
If you do turn that setting on, the app sends a small number of anonymous counts — never anything you wrote, never your session data, never identifiable to you personally. The rest of this document explains exactly what that means.
The following stays on your device, is never transmitted anywhere, and is never accessible to us in any form, under any setting:
There is no account to create, so there is no server-side profile of you to begin with. If you export your data (a feature in Settings), that export file is created and stored by your device's own share/save mechanism — we never receive a copy.
This setting is off by default. You choose it during onboarding, and you can change your mind at any time in Settings.
If it's on, the app sends small event records so we can tell whether people are still using the app a week after installing it — nothing more granular than that. Each event contains only:
session_complete), which numbered session it was — 1st, 2nd, 3rd, and so onThe complete list of six events. Nothing else is ever sent:
| Event | What it means |
|---|---|
install | The app was opened for the first time, ever, on this install. |
app_open | The app was opened today (sent at most once per day). |
onboarding_complete | The welcome screens were finished. |
session_complete | A session ended. Carries only the session number — never its duration, its anchor, its rep count, or anything about how it went. |
track_day_complete | A day of the 28-day track was completed. No further detail. |
paywall_view | The upgrade screen was shown. |
You can see this exact list — the same table above — inside the app at any time: Settings → "What's sent?"
What is never included in any of these events, under any circumstance: anything you wrote in the Gap Log, your session's duration or rep count or anchor or timing, your onboarding answers, your device's advertising identifier, your device model or OS version tied to you personally, your location, or anything that would let us reconstruct what a specific session or day was actually like for you.
If you opt in, the app generates a random identifier — not derived from your device, your account (there isn't one), or anything about you — and stores it only on your device. This identifier is what lets us tell "the same install opened the app on day 1 and again on day 7" apart from "a different install opened it once." It cannot be used to look up who you are, because nothing connects it to your name, email, or any other identifying information — we never collect any of those in the first place.
Resetting the app (Settings → Reset) generates a new identifier. A fresh install always gets a new one.
Event data (if you opt in) is sent directly to a server we operate. There is no third-party analytics company, advertising network, or data broker in this chain — no Google Analytics, no Firebase, no Meta SDK, nothing. We are the only party that ever receives this information, and we do not sell, rent, or share it with anyone else.
Comeback does not show ads and does not use advertising identifiers (such as Google's Advertising ID or Apple's IDFA) for any purpose.
Because there is no account and no identifying information collected, we have no way to look up "your" data specifically if you opted into analytics — the identifier is intentionally not linkable back to you. If you want your historical anonymous events removed from our server, contact us at the address below with the approximate dates you used the app and we'll do our best on a best-effort basis, though the anonymity of the data means we cannot verify a request corresponds to any particular installation.
Comeback is not directed at children and we do not knowingly collect information from anyone under the age of 13 (or the relevant minimum age in your jurisdiction). If you believe a child has provided us information, contact us and we will address it.
If this policy changes in a way that affects what's collected or why, we'll update the "Last updated" date above and, for material changes, surface a notice in the app itself.

This policy is written to be an accurate, plain description of what the app actually does, grounded directly in its source code and internal specification. It is not a substitute for legal advice — a qualified lawyer familiar with your jurisdiction (GDPR if you have EU users, DPDP if you have Indian users, CCPA if California) should review this before you rely on it for App Store / Play Store submission, particularly the children's-privacy and data-subject-rights sections, which vary meaningfully by jurisdiction.
