Privacy Policy — clir Hearing

Last updated: July 14, 2026

1. Who we are

clir Hearing (the "App") is provided by clir Technologies GmbH, Stremayrgasse 16, 8042 Graz, Austria (referred to as "clir", "we", "us"). We are the controller responsible for the personal data described in this policy. You can reach us at contact@clir.ai.

2. The short version

3. Data we process, and why

3.1 Microphone audio

When you start a listening session, the App captures audio from the microphone, enhances it (amplification and, in Clear Speech mode, on-device AI noise removal), and plays it to your connected headphones — all in real time, all on your device. This audio is not recorded, not stored, not transmitted to us or to anyone else, and not used to train machine-learning models. Processing stops the moment you end the session. Because this audio never leaves your device, it is not "collected" within the meaning of data protection law.

3.2 Account data

If you create an account or sign in with Google, we process your email address, your name, and internal authentication identifiers through Firebase Authentication (a Google service). We use this to operate your account, to keep your free-session allowance and subscription status in sync across reinstalls, and to let you delete your account. Legal basis: performance of a contract (Art. 6(1)(b) GDPR).

3.3 App activity data

We store the number of free sessions you have used and your subscription/entitlement status, keyed to your account identifier, in Google Cloud Firestore / Firebase Realtime Database. Legal basis: performance of a contract (Art. 6(1)(b) GDPR).

3.4 Usage analytics

We use Google Analytics for Firebase to understand how the App is used: interaction events (for example session started, listening mode switched, store screens viewed), device model, operating-system version, App version, language and region, an app-instance identifier, and the identifier for vendors (IDFV). The advertising identifier (IDFA) is included only if you have allowed tracking (see 3.6). Legal basis: our legitimate interest in improving the App (Art. 6(1)(f) GDPR).

3.5 Crash and performance diagnostics

We use Firebase Crashlytics to receive crash reports: stack traces, the state of the device at the time of the crash (model, OS version, free memory), and the App version. Crash reports are not tied to your name or email. Legal basis: our legitimate interest in keeping the App stable (Art. 6(1)(f) GDPR).

3.6 Advertising measurement (only with your consent)

We use the Meta Platforms SDK to measure the effectiveness of our advertising on Facebook and Instagram. If — and only if — you allow tracking in the iOS permission dialog (App Tracking Transparency), app events such as first launch and subscription purchases, together with device identifiers including the advertising identifier (IDFA), are shared with Meta Platforms Ireland Ltd. / Meta Platforms, Inc. and matched against Meta's ad systems. If you decline, no cross-app identifiers are shared and only aggregated, privacy-preserving attribution remains. Legal basis: your consent (Art. 6(1)(a) GDPR). You can withdraw consent at any time in iOS Settings → Privacy & Security → Tracking.

3.7 Purchases

Subscriptions and one-time purchases are processed entirely by Apple. We never receive your payment details. Apple provides us with transaction and entitlement confirmations (product purchased, price tier, timestamps) so the App can unlock what you paid for. Purchase events are also logged to the analytics and ad-measurement services described in 3.4 and 3.6. Legal basis: performance of a contract (Art. 6(1)(b) GDPR).

4. What we do not collect

The App does not collect recordings of your surroundings, your contacts, your photos, your precise location, or health data. Should a future version offer features that process hearing-related profiles, we will update this policy and ask for your permission first.

5. Recipients of data

We use the following processors and recipients:

We do not sell personal data to anyone.

6. International transfers

Some of the providers above process data in the United States. Transfers are protected by the EU-U.S. Data Privacy Framework and/or the European Commission's Standard Contractual Clauses.

7. How long we keep data

8. Your rights

Under the GDPR you have the right to access, rectify, and erase your personal data, the right to restrict or object to processing, the right to data portability, and the right to withdraw any consent at any time with effect for the future. To exercise these rights, email contact@clir.ai. You also have the right to lodge a complaint with a supervisory authority, in particular the Austrian Data Protection Authority (Datenschutzbehörde, dsb.gv.at).

California residents: we do not sell personal information. To the extent that sharing device identifiers with Meta for ad measurement constitutes "sharing" for cross-context behavioral advertising under the CCPA/CPRA, you can opt out by declining (or later disabling) tracking in iOS Settings → Privacy & Security → Tracking, or by contacting us at contact@clir.ai. We do not discriminate against you for exercising your privacy rights.

9. Children

The App is not directed at children under 13 (or the higher minimum age of digital consent in your country), and we do not knowingly collect personal data from them. If you believe a child has provided us personal data, contact us at contact@clir.ai and we will delete it.

10. Security

All data in transit is protected with TLS. Data at rest is stored with the reputable providers listed in section 5, protected by access controls and industry-standard safeguards.

11. Changes to this policy

We will post any changes on this page with an updated date. If a change is material, we will additionally inform you in the App before it takes effect.
