Privacy policy

Effective 1 October 2026

Speeku is built so your learning can stay yours. Everything the app does with your voice happens on your phone, not on Speeku servers.

On your deviceYour voice, profile and progress are processed and kept on your phone.
No Speeku cloudWe do not receive your lesson activity or use it for analytics, advertising, or AI training.
You stay in controlRemoving the app removes the app’s locally stored learning data, subject to your device backups.

1. Who is responsible?

Data Stand AI GmbH, Uetlibergstrasse 88, 8045 Zurich, Switzerland, is the controller for the limited personal data described in this policy. Speeku is a product of Data Stand AI GmbH. Full publisher details are listed in our Imprint. Privacy questions can be sent to contact@speeku.com.

2. Data used by the app

Voice and microphone

The microphone is active only while you are taking part in a speaking lesson. The app compares the audio, on your phone, with the phrase you were asked to say, and then discards it: it is never saved, uploaded or sent to us. Microphone access can be withdrawn in your device settings.

Learning data

Your settings, learning level, vocabulary and lesson progress are stored locally so the app can personalize lessons and continue where you left off. We cannot view this data and do not use it for advertising, tracking, profiling outside the app, or training models.

On-device speech model and recordings

Speeku uses a speech model that checks a phrase you say against the phrase you were asked to say, and recordings of the course’s words and sentences made in advance. These assets are downloaded to your phone once, or delivered with the app, and then used locally. A download request necessarily reveals ordinary connection information (such as IP address, time, and requested file) to the app store or file host that delivers the asset, but no voice or learning content is included in that request.

3. Data we do not collect through the app

4. Website and contact

This website uses Google Analytics on its landing pages to count visits, see which pages are read and whether a store button was pressed, and to tell whether our Google ads bring visitors who go on to a store. It does not run until you agree to it. A band at the foot of the page asks the first time you arrive, and nothing is loaded from Google and no cookie is set unless you press Accept. If you accept, two first-party cookies are set for 180 days, the reports we see are aggregate, and Google Ireland Limited processes that data on our behalf, which may involve transfer to Google servers outside Switzerland and the European Economic Area. Every cookie is named, with what it does and how long it lasts, in our Cookie Policy, which is also where you change your answer. The site sets no advertising cookies, runs no cross-site tracking, and loads no third-party fonts. Like nearly every website, its hosting provider may temporarily process technical request data such as IP address, browser information, requested page, and time to securely deliver the site and prevent abuse. If you email us, we receive your email address, message, and any information you choose to include, and use it only to respond and maintain necessary correspondence.

5. App stores and device services

Your app store, operating-system provider, internet provider, or backup provider may independently process data under its own terms. Speeku does not control those services. If device backup is enabled, locally stored app data may be included in a backup managed by your device provider.

6. Retention and deletion

App data remains on your phone until you clear it in the app or device settings, or uninstall the app. Model assets remain until removed with the app or by a supported storage control. Website security logs are kept only as long as reasonably necessary for security and operation. Contact messages are retained while needed to answer your request and meet applicable record-keeping duties.

7. Your rights

Depending on where you live, you may have rights to information, access, correction, deletion, restriction, objection, or data portability. Because we do not receive your in-app learning data, we cannot access or delete it for you; you control it on your device. For data you send us directly, contact us at the address above. You may also complain to your local data-protection authority.

8. Children

Speeku is a general-audience learning app and is not directed to children below the minimum age required to use digital services independently in their country. A parent or guardian should supervise use where local law requires it.

9. Security and changes

Keeping sensitive learning activity on-device reduces exposure, but no device or software is completely secure. Keep your operating system updated and protect your device. We may update this policy when the product or law changes; the effective date above will show the latest revision. Material changes will be highlighted where appropriate.
