Privacy Policy
The short version: Supplement Streak keeps your supplement routine on your iPhone. There is no account or server that stores your routine. Optional app recommendations use aggregate view and open counts. The free version is funded by advertising from Google, which is loaded only after you have been asked for consent and which sends Google technical data about your device, never your routine. Supplement Streak Pro removes the advertising.
Recommendations for our other apps
In Settings, the app can fetch up to three recommendations for our other apps. The choices depend on the app you are using, App Store availability and iOS compatibility, not on your personal data or activity inside the app. App icons load from Apple’s image servers. Opening a recommendation takes you to the App Store with a campaign label identifying the source app and placement, never a person.
We count qualified views and successful opens in aggregate. Our service stores daily counts with the source app, recommended app, placement, configuration revision and optional presentation variant. It does not store an account, advertising identifier, device identifier, persistent visitor identifier or personal profile, and it does not receive the app’s private content. These counts cannot tell us who installed an app.
The recommendation service is hosted by Supabase. Network requests necessarily expose an IP address to the hosting provider for delivery and security; our aggregate counter does not store it. See Supabase’s privacy policy. Apple processes icon requests and App Store visits under Apple’s privacy policy.
1. Who we are
Supplement Streak ("the app", "we") is an iOS supplement-habit tracker. This policy explains how the app handles information.
2. Data we collect
Nothing you enter. The app does not require an account and does not collect personal information. All content you create (your supplements, doses, reminder times, intake logs, streaks, and notes) is stored locally on your device using Apple's on-device storage and, where enabled, an App Group container shared only with the app's own widgets on the same device. It is never sent to us, and it is never handed to the advertising kit described in section 3.
Two things do use the network, and neither of them touches that content: Apple's App Store and StoreKit, which deliver the app and handle the subscription described in section 5, and the advertising in the free version, described in section 3.
3. Advertising in the free version
The free version of Supplement Streak shows advertising. It appears as a banner strip below the tab bar, which means it is present on all five tabs of the app, and it appears once as a full screen advert after you close the share sheet for a streak card. The full screen advert is never shown during your first session with the app, and never within three minutes of the previous one. Supplement Streak Pro removes the advertising entirely.
The adverts are delivered by the Google Mobile Ads SDK. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, for users in the European Economic Area, the United Kingdom and Switzerland, and Google LLC elsewhere. To fill an advert slot, Google receives technical data from the device such as an IP address, device and operating system characteristics and, if you allow it, an advertising identifier.
| Data type | Processed by the app | Reaches a third party |
|---|---|---|
| Supplements, doses, reminder times, intake logs, streaks, notes | Written to your device only | No. It is never passed to the advertising kit or to anyone else |
| Advertising identifier (IDFA) | Only if you allow it in the App Tracking Transparency prompt | Google, for advertising, and only with your permission |
| Technical request data for an advert | Sent by Google's kit when an advert is loaded | Google, on the basis of your consent |
| Contact details, location, purchase history | No | No |
Your consent comes first. Before the advertising kit is started at all, the app shows Google's User Messaging Platform consent form, and iOS then asks its own App Tracking Transparency question. Only after that does any advert load. The legal basis is your consent, Art. 6(1)(a) GDPR, and you may withdraw it at any time with effect for the future: open the Settings tab inside the app and choose Ad Privacy Options, which the app shows wherever Google's consent framework requires it. Buying Supplement Streak Pro removes the advertising altogether.
Google's own processing is described at policies.google.com/privacy and, for advertising specifically, at business.safety.google/privacy. Beyond Google's advertising kit and the aggregate recommendation counts above, the app contains no analytics service, no attribution SDK and no crash reporting SDK.
4. Notifications
Reminders are delivered as local notifications scheduled on your device. They are not sent through any server and contain only the information you entered (such as a supplement name and time). You can disable notifications at any time in iOS Settings.
5. Subscriptions and payments
Supplement Streak Pro is an auto-renewable subscription processed entirely by Apple through the App Store. We never see or receive your name, payment card, or Apple Account details. Purchase validation happens on-device through Apple's StoreKit. Apple's handling of your purchase is governed by Apple's own Privacy Policy.
6. Data sharing
We sell nothing and we receive nothing. Your supplement routine is not shared with anyone, because it never leaves your device. The only data that reaches a third party is what Google needs to fill an advertising slot in the free version, described in section 3, and what Apple processes to deliver the app and handle the subscription, described in section 5.
7. Data retention and deletion
Your data lives only on your device. To delete all of it, simply delete the app. Its on-device storage is removed with it.
8. Children's privacy
The app is intended for a general audience and is not directed at children. We do not knowingly collect personal information from children.
9. Changes to this policy
If this policy changes, we will update this page and revise the "Last updated" date above.

11. Measurement on this website
The marketing pages of this site use Vercel Web Analytics. It is cookieless: it sets no identifier and builds no profile. It counts page views and clicks on the App Store button, and for a click it records which button on the page was used and the path of the page that button sits on. Nothing is evaluated per person and nothing from it is passed on to a third party.
The provider is Vercel Inc., 440 N Barranca Avenue #4133, Covina, CA 91723, USA. Its privacy policy is at vercel.com/legal/privacy-policy.
