Onseol counts the days that matter — no account, no sign-up, and your dates never leave your phone. The free version shows ads; the one-time Pro removes them.
We do not collect any personal data. There is no account, no analytics SDK, and nothing you create — your events, dates, titles or notes — is ever uploaded. The one exception is the advertising in the free version, where Google processes device data to choose and measure ads; see “Advertising” below.
None of your content. We do not collect, transmit, sell, or share your events or any personal data, and we operate no servers that receive it. We ship no analytics or crash-reporting SDK of our own. What the ad SDK sends to Google is described next.
Free use is ad-supported: a short ad after you save an event, plus an optional ad you can choose to watch to add one event beyond the free five. Ads are served by Google AdMob. To do that, Google processes your advertising identifier, an approximate region derived from your IP address, device and app information, and your interaction with the ad, under Google’s privacy policy. We only ever see aggregate revenue reporting — never anything about an individual person.
In the EEA, Switzerland, and the UK, a Google consent form (UMP) asks for your choice before the first ad loads. You can change it at any time from Settings → Privacy options in the app. On iOS the system additionally asks whether the app may track you across apps and websites; if you decline, you still see ads, but they are not personalized.
The one-time Pro upgrade removes advertising completely. For buyers the ad SDK is never initialized, and neither the consent form nor the iOS tracking prompt appears. Your events and dates are never sent to Google or anyone else, with or without Pro.
Reminders (“D-7”, “D-DAY”, anniversary milestones) are local notifications scheduled on your device by the operating system. They are not sent from any server, and no data leaves your device. You can turn them off in your device Settings at any time.
The optional one-time “Pro” upgrade is processed entirely by Apple (App Store) or Google (Google Play). We never see or store your payment details; those transactions are handled under Apple’s and Google’s own privacy policies. We store only a local on-device flag indicating whether the upgrade is active.
Onseol is not directed at children and collects no data of its own from anyone. The free version does show ads, however, and an ad can lead to an external site. The one-time Pro upgrade removes advertising for anyone who would rather use the app without it.
Because all data lives on your device, you are in full control: deleting an event removes it, and deleting the app removes all of its data from your device.
If this policy changes we will update the “Last updated” date above and, for material changes, note it in the app or store listing.
