On Deck

Her cycle, quietly understood.

On Deck helps you keep track of your partner's cycle, so you know where she is and what today calls for.

It runs on your device. The app itself makes no network requests, and there is no account, no ads, no third-party SDKs, and no server of ours anywhere — which means there is no copy of your data outside your own phone.

Privacy in one line

We collect nothing. If anyone — including law enforcement — asks us for your records, there is nothing for us to hand over, because the data never leaves your device.

Support

Questions, bug reports, or feature requests — email yzd3008@icloud.com. We usually reply within a few days.

There is no account to recover and no server-side data to restore. If you have lost your records, the only copy was on your device — restore it from a backup file you exported earlier.
