Privacy Policy

Last updated October 4, 2026

In short: Speech Zen works on your phone. It listens through your microphone only while you have it switched on, and it never records, stores or sends what it hears. Live captions are made on your phone too. The only things that ever leave your phone are feedback you choose to send us and what's needed to manage a subscription. There are no ads, no analytics and no tracking.

Who we are

Speech Zen is an app developed by DreamCircuit Labs ("we", "us"). This policy covers the Speech Zen app and the speechzen.com website.

Microphone audio

Speech Zen needs your microphone to do its job: it cleans up the sound around you and plays it back, slowed down when people talk fast. That audio is processed in real time on your phone and discarded right away. It is never saved to storage or sent over the internet, and we never have access to it.

Speech Zen only uses the microphone while listening is switched on. When it keeps listening in the background on Android, your phone shows a "Speech Zen is listening" notification so you always know, and you can stop it from there. On iPhone, the microphone indicator at the top of the screen shows whenever Speech Zen is listening.

Say that again keeps the last few seconds of cleaned-up sound in the phone's memory while you listen, so it can play them again. That short stretch is constantly overwritten, is never saved, and is gone as soon as you stop listening.

Live captions

If you turn on captions, the words are worked out by your phone's built-in on-device speech recognition. Speech Zen only uses on-device recognition for captions, so the audio stays on your phone. The captions are shown on screen and are not saved.

Voice questions to the helper

If you tap the microphone in the built-in helper to ask a question by voice, your phone's own speech recognition service (for example, Google's, or Apple's dictation on iPhone) turns your speech into text. That service is provided by your phone, not by us, and its handling of your voice is covered by its own privacy policy. Speech Zen only receives the resulting text, uses it to answer you on your phone, and doesn't keep it. Typing your question avoids this entirely.

Feedback you send us

If you send feedback (from Settings or through the helper), we receive what you wrote, the kind of feedback (bug, idea or general), your email address only if you choose to give one so we can reply, and basic technical details to help us fix problems: the app version, your phone's system version (Android or iOS) and, on Android, its make and model. We use this only to improve Speech Zen and to reply to you. Nothing is sent unless you tap Send.

To prevent spam, our server briefly keeps a scrambled (hashed) form of the sending network address for about two hours. It can't be turned back into the address.

Subscriptions and payments

Through Google Play: Google handles the purchase and your payment details; we never see them. The app asks Google Play whether your subscription is active. See Google's privacy policy for how Google handles purchases.

Through the App Store: Apple handles the purchase and your payment details; we never see them. The app asks the App Store whether your subscription is active. See Apple's privacy policy for how Apple handles purchases.

Through speechzen.com: payments are handled by Stripe, which processes your card details; we never see or store them. We receive the email address you enter (for your receipt and your code) and the status of your subscription. We keep, linked to your code, your subscription's status and renewal date, your email address, Stripe's customer and subscription references, and, if you completed the setup questions, the settings they produced (such as volume and tone levels). When the app checks your code, it sends only the code. Stripe's handling of your information is covered by Stripe's privacy policy.

The setup questions on speechzen.com are answered in your browser. If you get a code, only the resulting settings are saved with it, not your individual answers.

Information stored on your phone

Your settings (such as volume, tone and slowdown strength), whether you've done the setup, a few counters used to decide when to ask for a rating, and your subscription status are saved only on your phone so they're there next time. They're deleted if you uninstall the app.

Ratings

Now and then, after you've used Speech Zen for a while, the app may show Google Play's or the App Store's own rating prompt. Any rating or review you leave goes to Google Play or Apple, not to us.

Permissions

Sharing and selling

We don't sell your information or share it for advertising. We share it only with the services that process it for us as described above (Google Play, Apple's App Store, Stripe, and Cloudflare, which hosts speechzen.com and stores feedback and codes), or if the law requires it.

Keeping and deleting your information

Feedback is kept until we've dealt with it, then deleted. Subscription records are kept while your subscription is active and for as long as we're legally required to keep payment records afterward. To have your feedback or code records deleted, or to ask what we hold about you, email us at the address below.

Children

Speech Zen isn't directed at children under 13, and we don't knowingly collect information from them.

Changes to this policy

If this policy changes, we'll update it on this page and change the date above.
