Privacy Policy — TABATA Power

Last updated: 16 August 2026 · Applies to TABATA Power v1.0.0 and later.

This policy applies to TABATA Power — both the free version and TABATA Power Pro (they are the same app). Other apps published by BIKINTULIS have their own policies — see the directory.

1. Who we are

BIKINTULIS is an independent developer of Garmin Connect IQ apps. For questions about this policy, use the contact form.

2. Summary in plain language

• TABATA Power runs entirely on your watch. It makes no network or web requests and talks to no server — there is no BIKINTULIS server involved at all.
• It needs no account and asks for no name, email, location or sign-in.
• Your saved workouts, personal bests and settings are stored only on the watch.
• Each session is saved as a standard Garmin cardio training activity (FIT), with one lap per round, which your watch syncs to your own Garmin Connect account just like any built-in activity — under Garmin's own policy (see section 7).
• It contains no advertising and no analytics.

3. Permissions this app requests

That is the only permission the app requests. It does not ask for internet/communications, and it does not ask for location, GPS or a heart-rate sensor permission. Heart rate is read from Garmin's standard activity information, which needs no permission prompt — so there is no location or heart-rate dialog to accept.

4. Data stored locally on the watch

• Your saved workouts — the moves you chose, their order, the work/rest/round timing and the name you picked for each.
• Personal bests — your best round count for each protocol.
• On the free version only: a count of completed workouts, used for the five free workouts. It is a simple counter on the watch — no server, no account.

This data stays on the watch and is removed when you uninstall the app. There is no cloud sync, no phone backup, no export and no sharing between watches — your saved workouts live on that watch only, so uninstalling loses them.

5. Data sent to a server

None. TABATA Power does not send any data off the watch to BIKINTULIS or to any third party — it has no networking code and contacts no server. The only data that ever leaves the watch is the standard Garmin activity (FIT) your watch syncs to your own Garmin Connect account, which is handled entirely by Garmin (see section 7).

6. What this app does NOT collect or send

• No name, email address, phone number, postal address, or account credential.
• No location or GPS data — the app does not request or read your position at all.
• No data sent to BIKINTULIS — there is no server contact whatsoever.
• No advertising or analytics SDKs of any kind.

7. Garmin Connect & your Garmin account

The app runs inside Garmin's Connect IQ platform and records a standard activity. When your watch syncs, that activity goes to your Garmin Connect account — exactly like any built-in activity. Garmin's own collection and use of data is governed by Garmin's policy at garmin.com/privacy. BIKINTULIS has no access to your Garmin account, your activities, or anything synced to Garmin Connect. If you set the Custom work, rest and round values from the Garmin Connect app's settings for this app, those choices are passed by Garmin to the watch and stored only on the watch.

8. The bikintulis.de website

Separate from the app, when you use the bikintulis.de website itself:

• If you leave a comment or review, your name, email, rating and comment text are stored. Your name, rating and comment are published publicly after moderation; your email is never published.
• If you use the contact form, your name, email, subject and message are stored privately and used to reply to you. If you attach a photo or video (optional, up to 20 MB), it is stored on the BIKINTULIS server alongside the message and only viewable by the site owner via an authenticated admin panel. The attachment is deleted when the message is deleted.
• Your IP address is stored in our database only as a salted SHA-256 hash (rate-limiting / spam prevention), never in raw form there. Raw IP addresses do appear in the standard web-server access log, as they do on any website; those logs are kept for up to 30 days and are used only for security and troubleshooting.
• Standard web-server access logs are kept up to 30 days.
• No third-party analytics, no advertising, no tracking pixels. The site sets exactly one cookie in total, and only on the Hyrox workout-builder page if you choose to pair a watch there.

9. Legal basis (GDPR)

Because the app itself collects and sends nothing to BIKINTULIS, the only personal data we process relates to the website: your consent (when you submit a comment or contact message) and legitimate interest (IP hashes and server logs, used solely to keep the site secure and operational).

10. Data retention

• On the watch: kept until you delete it or uninstall the app. No server copy exists.
• Website comments: retained while TABATA Power is listed on this site.
• Contact messages: retained as long as needed to handle your enquiry, then deleted.
• Server access logs: up to 30 days.

11. Your rights

Under the GDPR you can ask to access, correct, or delete data we hold (this only ever concerns website comments/contact messages — the app holds nothing on our side), withdraw consent, object to processing, or lodge a complaint with your data-protection authority. To exercise any right, use the contact form — requests are answered within 30 days.

12. Security

• The app makes no network connections, so there is no app-to-server traffic to secure.
• Any traffic to the bikintulis.de website is over HTTPS.
• No payment data is ever handled by BIKINTULIS — purchases go through the Garmin Connect IQ store.

13. Children

TABATA Power is a general-purpose fitness app, is not directed at children under 13, and does not knowingly collect any data from them (indeed, it collects no personal data from anyone).

14. Changes to this policy

This policy may be updated to reflect new features or legal requirements. The "Last updated" date at the top reflects the latest change. Continued use after a change indicates acceptance of the updated policy.
