Privacy Policy
Effective date: 14 November 2026. I take your privacy seriously. This notice explains what TideCup stores on your device, what (if anything) leaves the device, and how to contact me.
Alexandr Korsak (Bitscorp), a self-employed professional (autónomo) in Spain, operates the mobile application TideCup (co.bitscorp.tidecup). Bitscorp is a trading name, not a registered company. This page applies to TideCup on iOS and Android. The website
https://bitscorp.co has a separate
Privacy Policy and
Terms and Conditions.
The app
TideCup logs what you drink and estimates a daily water goal from the weight and activity you enter, plus an optional weather adjustment. Logs stay on the device. TideCup is not a medical device and does not give medical advice.
Data stored on your device
- Drink log (drink, amount, estimated hydration and caffeine), custom drinks, workout notes you type (calories and minutes), reminder settings, and the weight and activity you enter, in a local SQLite database.
- If weather adjustment is on, the last latitude, longitude, temperature, and humidity, in that same database.
- Local reminder notifications. Remote push notifications are not used.
- The current day progress for the iOS home-screen widget, in an app group on this device.
- If Apple Health sync is on, identifiers for the water and caffeine samples the app wrote.
Data that leaves your device
- Drink logs, weight, and caffeine totals are not uploaded to a Bitscorp server. There is no TideCup backend.
- If you turn on weather adjustment, the app reads your location while it is in use and sends that latitude and longitude to Open-Meteo for the current temperature and humidity. It does not send your name, drink log, or weight with that request.
- If you turn on Apple Health sync on iOS, TideCup asks permission to read and write dietary water and dietary caffeine, and it writes the drinks you log into Apple Health. This version does not import existing Health samples into the log, and it does not read steps, heart rate, or medical records. Android does not use Health Connect.
- If you send feedback, your email app may include the app version, build number, operating system, and device model in a message to alex@bitscorp.co.
- Purchase and subscription status are handled by Apple or Google and RevenueCat, as described below.
Permissions
- Notifications (optional): local reminders on this device.
- Location (optional, while in use): only if you enable the weather adjustment, to read a current position for that request. The app does not track you in the background.
- Apple Health (optional, iOS): read and write dietary water and dietary caffeine, only if you enable Health sync.
You can change or withdraw permissions in the operating system settings.
Sensitive information
Weight, drink history, and caffeine estimates can be health-related. They stay on your device, except for an optional Apple Health write and the latitude and longitude sent to Open-Meteo when weather adjustment is on.
Analytics and crash reporting
TideCup does not include a third-party analytics or crash-reporting SDK. I do not run Mixpanel, Google Analytics, Firebase, Sentry, or a similar product inside this app. The stores and RevenueCat may keep their own purchase or install records under their policies.
Third parties
I only involve the parties below for the purposes stated. Each has its own privacy policy.
- RevenueCat: To check and restore your Pro entitlement. RevenueCat receives purchase tokens, subscription status, and an anonymous app user identifier. It does not receive the journal, photos, files, or other content you keep in the app.
- Apple: If you buy or manage a subscription or a lifetime purchase on the App Store, Apple processes the payment. We do not receive your full payment card number. If you sync Apple Health, dietary water and caffeine samples you log are written to Health on your device under Apple policies.
- Google: If you buy or manage a subscription or a lifetime purchase on Google Play, Google processes the payment. We do not receive your full payment number.
- Open-Meteo: Optional. If you turn on weather adjustment, Open-Meteo receives the latitude and longitude of your current position and returns temperature and humidity. It does not receive your drink log, weight, or name.
Accounts, servers, and retention
No Bitscorp server. Logs stay in on-device SQLite. The only network call that carries location is the optional Open-Meteo weather request. Purchase checks use the app stores and RevenueCat.
TideCup does not require a Bitscorp account. Information stored only on your device remains there until you delete it in the app or uninstall the app. Purchase records are kept by Apple or Google and by RevenueCat for as long as they need them to provide the subscription. If you email me, I keep the message long enough to respond and then delete it when it is no longer needed.
Your rights
Because most TideCup content never leaves your device, the practical way to access or delete it is in the app, or by uninstalling the app (which removes local data). For any personal data I hold in email, or questions about purchase records, write to
alex@bitscorp.co. If you live in the European Economic Area, the United Kingdom, or another region with similar rights, you may also request access, correction, deletion, or a restriction of processing of personal data I hold, and you may lodge a complaint with your local supervisory authority. In Spain that authority is the Agencia Española de Protección de Datos (AEPD).
International processing
I am based in Spain. Apple, Google, and RevenueCat may process purchase data in other countries. Their policies describe those transfers.
Changes to this policy
This Privacy Policy is effective as of 14 November 2026. I may update it from time to time. The current version will always be at
https://bitscorp.co/tidecup/privacy. Material changes will be reflected on this page, and I may also note them in the app.
