Privacy Policy — Lingua

Last updated: 16 August 2026 · Applies to Lingua v1.0.4 and later (the Location permission described below was added in v1.0.4, for on-device sunrise/sunset).

This policy applies to the Lingua Garmin Connect IQ watch face, in both listings: the free Lingua Trial and the paid Lingua. They are the same face and behave identically for privacy. 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 and watch faces. For questions about this policy, use the contact form.

2. Summary in plain language

  • Lingua runs entirely on your watch. It makes no network or web requests and talks to no server — there is no BIKINTULIS server involved. The learning phrases are built into the watch face.
  • It requests a single permission — Location (Positioning) — used only on the watch to work out your local sunrise and sunset times. Your location is never stored by us and never sent anywhere. No other permission is requested.
  • It displays values Garmin already makes available to watch faces — weather, sunrise/sunset, steps, calories, altitude, battery and heart rate — purely to show them on screen. These values are never stored by us and never sent anywhere.
  • The free trial's 24-hour timer runs on the watch itself (a first-launch timestamp in local storage) — no server, no account.
  • It asks for no name, email or account, and contains no advertising or analytics.

3. Permissions this watch face requests

Lingua requests a single permission — Location (Positioning). It uses your watch's last-known location, on the device, purely to calculate your local sunrise and sunset times for the data face. That location is used only to draw those times; it is never written to storage, never sent to BIKINTULIS, and never sent anywhere — the face has no networking at all. Both the free Trial and the paid Lingua behave identically.

Lingua does not request internet/communications or any external-sensor permission. The other values it shows — weather, steps, calories, altitude, battery and heart rate — are read through the standard information Garmin already provides to every watch face and need no permission.

4. Data stored locally on the watch

Lingua stores only your display settings in Garmin's per-app storage sandbox, accessible only to this watch face:

  • Language pair (which of the 10 languages you're learning and which is your own)
  • Difficulty level (Words / Phrases / Sentences)
  • Phrase rotation (every wrist-up, or every 1 / 4 / 24 hours)
  • Theme (Rich data / Clean text-only / Compact split) and any colour/format options
  • On the free Trial only: a first-launch timestamp used to run the 24-hour trial timer

These settings stay on the watch, keep no history, and are removed when you uninstall the face. The weather, steps, heart rate and other values shown on the face are read live and displayed only — they are not written to storage.

5. Data sent to a server

None. Lingua has no networking code and contacts no server — nothing about you or your watch ever leaves the device, including any value it displays and the trial timer. (A future version could add an optional cloud feature; if that ever happens, this policy will be updated before it ships and the change will be described here.)

6. What this watch face does NOT collect or send

  • No name, email address, phone number, postal address, or account credential.
  • Your location is used only on the watch to compute your local sunrise and sunset — it is never transmitted, and no position data is sent anywhere.
  • No transmission of location, weather, activity, or sensor data — it displays these values on the watch and sends none of them anywhere.
  • 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 watch face runs inside Garmin's Connect IQ platform. 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 your options from the Garmin Connect app's settings for this face, those choices are passed by Garmin to the watch and stored only on the watch.

8. The bikintulis.de website

Separate from the watch face, 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 watch face 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: your settings are kept until you uninstall the face. No server copy exists.
  • Website comments: retained while Lingua 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 watch face 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 watch face 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.

13. Children

Lingua is a general-purpose watch face, 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.
