Privacy & Support

Onseol counts the days that matter — with no account, no ads, and no tracking. Your dates stay on your phone.

Effective 22 June 2026 · Last updated 22 June 2026

The short version

Onseol does not collect any personal data. There is no account, no analytics, no advertising, no tracking, and no third-party SDK that sends your information anywhere. Everything you create stays on your device.

What we store, and where

Data we collect

None. We do not collect, transmit, sell, or share any personal or usage data. We operate no servers that receive your data, and we ship no analytics or crash-reporting SDK that phones home.

Notifications

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.

Purchases

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.

Children

Onseol collects no data from anyone, including children. It is safe for all ages with respect to privacy.

Your control

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.

Changes to this policy

If this policy changes we will update the “Last updated” date above and, for material changes, note it in the app or store listing.

Support & contact
