Dicera Privacy Policy

Last updated: 2 November 2026

No one is listening. Nothing is saved. This page is the legal version of that sentence.

Who we are

Dicera (formerly Sayable) is published by Overpass Limited, a company registered in England and Wales (Company No: 05074817). Our registered address is 124 City Road, London, EC1V 2NX.

Questions: support@overpass.co.uk or eric@overpass.co.uk.

This policy covers Dicera only. Other Overpass apps are covered by the mobile apps privacy policy.

Your voice is never stored

Your speech is turned into text for the sentence you are on, and then it is gone. We do not write audio to the phone. We do not upload a recording to our servers. We do not keep audio to train a model -- ours or anyone else's.

Speech recognition runs on the device by default. If you later enable an optional cloud grader or pronunciation check, only what that turn needs is sent, for that turn. Audio is not retained. Transcripts are not used for training. There is no setting to "opt out of training" because there is nothing to switch off.

What stays on the phone

Dicera keeps lesson progress and settings locally, including:

  • Which items you have practised and when they are due again
  • A learner profile (pace, entitlement, language)
  • Nerves ratings -- how you feel about speaking. These never leave the device and are never used to group you with anyone

Uninstalling the app deletes this data from the device unless you have signed in and chosen to sync.

What we do not do

  • We do not store your voice
  • We do not use your speech to train models
  • We do not show advertising
  • We do not use advertising SDKs or fingerprinting
  • We do not track you across apps
  • We do not sell personal data

That is why Dicera never shows you a tracking prompt. There is nothing to prompt about.

Sign-in, purchases, and analytics

If you sign in with Apple, Apple provides an identifier (and an email address only if you choose to share one). We use that to restore purchases and, if sync is enabled, to keep progress across devices.

Subscriptions and one-off purchases are processed by Apple. We do not see or store your card details.

If analytics are switched on, they are anonymised usage and crash events (for example app opens and which screen you were on). They are not recordings, not transcripts, and not nerves ratings.

Children

Dicera is a language course for adults. It is not directed at children under 13. We do not knowingly collect personal information from children.

Your rights

Under UK GDPR you can ask what personal data we hold, ask for a copy, ask us to correct it, or ask us to delete it. Because voice is never stored, there is no recording to hand over. Progress on the phone is yours to delete in Settings or by uninstalling.

You can also complain to the Information Commissioner's Office at ico.org.uk or 0303 123 1113.

Changes

If this policy changes, we will update the date on this page. The product promise does not change: your voice is never stored.
