This policy is for TapYes, published by Tidalux Ltd. TapYes is a working-memory reminder. It is not a clinic, not the NHS, not a medical device, and not medical advice. The listing is for ages 18 and over. TapYes is not in Designed for Families, and it is not directed at children under 13.
Questions: support@tidalux.io. Studio: apps@tidalux.io.
What stays on your phone
The name on Yes, reminder time, how loud, look, colour, optional cutoff, optional cues, optional supplements, further reminders if you have Keep, and Yes logs stay on this device (or in this browser). Yes logs are never sent to Tidalux.
On a phone, that store is encrypted on device. Uninstalling TapYes, or clearing TapYes storage, removes it.
Optional Google spare key
You can skip Google. TapYes still works. If you choose the spare key, TapYes asks Google for
openid only. No email scope. No contacts. The app keeps a hashed Google user id on
the device so it can recognise the same spare key later. The test account for a review build is
tidaluxltd@gmail.com. No password is published with the app.
If a backup host is switched on, Tidalux stores only that hashed id, a sealed box, and an Argon2id wrap of the key. The eight words that open the wrap stay on your devices. They are not uploaded, so we cannot read the medicine names or the Yes taps inside the box. If no backup host is on, nothing from TapYes is sent to Tidalux.
Payments
The reminder, all three nag levels, and the on-device save are free. Keep is optional: £0.99 a month, or £4.99 once. On Android that charge goes through Google Play. On iPhone it goes through Apple. On this website it goes through Stripe. A receipt stores a product id, an expiry, and a store source. It does not store the medicine name or a Yes log.
What we do not do
No ads. No analytics SDK. No crash reporter. No sale of data. No streaks sold to anyone. We do not use your data to train models. We do not show third-party advertising.
Notifications
Reminders are scheduled on the device at the intensity you pick. Once is the default. Sound is never the default. We do not use those notifications to collect data. A closed browser tab is not an alarm. The installed app is.
Children
TapYes is not directed at children under 13. We do not knowingly collect data from children.
How long we keep it
On-device data stays until you delete the app, clear storage, or overwrite it in Options. Server backup, if any, stays until you ask us to delete it, or you overwrite it with a new spare-key save. A payment receipt stays until the store subscription ends, or until you ask us to delete the spare-key record.
Your requests
Delete the optional account and any associated server box: tapyes.ch/delete.html
Delete data without deleting the account: tapyes.ch/delete-data.html
We aim to action email requests within 14 days. Usually it is faster.
