Terms of Use

Last updated: 28 October 2026

By using OneFlip you agree to these terms. Apple’s Licensed Application End User License Agreement also applies to your copy of the app; where these terms are silent, Apple’s govern.

OneFlip flips a fair coin and helps you remember what you decided. It is a tool for reflection, not advice — not medical, legal, financial or professional advice of any kind. The coin knows nothing about your situation. Every decision, and every consequence, is yours.

Each flip is one bit from your device’s cryptographic random number generator. We do not weight, bias or predict outcomes, and no result is adjusted based on what came before. Randomness means randomness: a run of the same side is normal, not a fault.

What you write about your decisions, the labels you give the sides and any photo, video or voice note you attach to a note are yours. We claim no license to them, we cannot see them, and we cannot recover them if you lose your device — only your device backup or iCloud sync can.

Your journal lives on your device and, if you keep iCloud sync on, in the private iCloud of your Apple Account. You are responsible for keeping access to your device and your Apple Account: we cannot read your journal and hold no copy of it, so we cannot restore access or recover anything on your behalf.

OneFlip Pro unlocks an unlimited journal, the Stats tab — follow-through, the Patterns charts, tag breakdowns and My year in flips — unlimited label presets, the journal lock, every coin skin, your recent notes on the iPad extra-large widget, and your streak count past day 3 — in the app, on medium and large widgets and on watch faces. It is offered as a monthly or a yearly auto-renewing subscription, or as a one-time lifetime purchase. The price and any introductory offer are shown before you buy and are charged to your Apple Account at confirmation. Auto-renewing plans renew at the end of each period, and your Apple Account is charged within 24 hours before that period ends, unless you cancel at least 24 hours before it ends. The lifetime option is a one-time purchase and does not renew. Manage or cancel in Settings → your Apple Account → Subscriptions; deleting the app or your data does not cancel a subscription. If a renewal payment fails, Apple keeps Pro active for up to 16 days while it retries; the app warns you, and tells you how long is left when Apple gives it a date. If it still fails, Pro ends and the journal shows the 3 most recent notes again. Refunds are handled by Apple, not by us — request one at reportaproblem.apple.com, or in Settings → your Apple Account → Purchase History.

Without Pro you can flip as often as you like, and your journal keeps 3 notes; after that, saving a new one needs Pro. Nothing you already wrote is ever deleted to make room. If your journal holds more than 3 notes without Pro — from Pro that has ended, or synced from another device — all of it stays in your journal: it shows the 3 most recent, and the rest comes back with Pro. In that case, saving a new note needs Pro too, just as it does for anyone at the free limit. Your label presets work the same way — the 3 most recent are shown, the rest wait for Pro, and saving more than 3 presets needs Pro. Exporting your journal is free either way, including the notes the list is not showing. If Pro lapses, the journal lock switches itself off, so you never end up locked out of your own journal.

Use OneFlip lawfully. Do not reverse-engineer or tamper with the app, and do not attempt to circumvent the paid features or their verification.

OneFlip is provided as is. We do not promise it will be free of defects or available without interruption, and to the extent the law allows we are not liable for indirect or consequential loss arising from its use. Nothing here limits your rights under the consumer law of your country. You can stop using OneFlip at any time by deleting it; if we discontinue the app or a feature, purchases already made remain governed by Apple’s terms.

These terms may change as OneFlip evolves — the version inside the app is the current one. Questions: oneflip.app@gmail.com.
