Privacy Policy

Alketo translates text, speech and photographs. This page explains, in plain language, what happens to what you type, say and photograph.

The short version.
  • Alketo has no accounts. We never ask for your name, e-mail or phone number.
  • Your translation history and your glossary stay on your phone.
  • Photographs never leave your phone — text is read from them on the device.
  • No advertising, no analytics, no tracking across apps or websites.
  • What you translate does pass through our server to a translation provider. We do not store it and never write it to our logs.

What we process, and why

Text you want translated. It goes to our server, on to the translation provider, and back to you — then it is discarded. Our logs record only the length of the text, the languages and how long it took. Never the text itself.

Sound from the microphone. Speech is normally recognised on your phone and the recording never leaves it. For languages your phone cannot recognise, the app may send the recording to our server, which passes it to a speech-recognition service. The recording is not stored and is excluded from our logs.

Text read from photographs. The photograph itself never leaves your phone; the text is read on the device. Only the recognised text is sent onward, exactly like text you typed.

A device number. The first time the app runs, it makes up a random number for itself. It is not taken from your phone, your SIM card or you, and it cannot identify you. We hold it on the server to count your free monthly usage and to stop strangers spending our credit. It is the only thing we keep about you — and we keep it only in the server's memory, so it is lost whenever the server restarts and reset at the start of every month.

Group rooms. Messages pass through our server so they can be translated and handed to the other people in the room. They live in memory only for as long as that takes and are never written to disk. We count how many messages and in which languages — never what was said.

What stays on your phone and nowhere else

Deleting the app deletes all of it. We have no copy to delete.

Who else sees your text

We do not build the translation ourselves. To make it, your text is passed to a provider:

Provider Used for What they say about keeping it
Anthropic (Claude) Most translations Inputs and outputs are deleted within 30 days, and are not used to train models without express permission.
Speech recognition service Only languages your phone cannot recognise Receives the recording in order to transcribe it.
We would rather say this plainly than claim that nothing ever leaves your phone. It does leave — that is how a translation gets made. What we promise is our own part: we do not keep it, and we do not log it.

What we never do

Permissions the app asks for

Permission Why
Microphone Voice and live interpreting
Camera Translating text from what you photograph
Photos (read) Choosing an existing picture instead of taking one

Each can be refused, and refusing it only turns off that one feature.

Your rights

Under the GDPR you have the right to see, correct, export and erase personal data held about you. In practice there is almost nothing to act on: we hold no name, no e-mail and no account, and the one thing we do hold — the random device number — is in memory only and disappears by itself. Everything else is on your phone, where deleting the app erases it.

If you want to ask us anything about this, write to us at the address below. Please note that because we cannot connect you to a device number, we cannot look you up — and we consider that a feature, not a shortcoming.

Children

Alketo is not aimed at children and we do not knowingly collect anything about them. There is nothing to collect: there is no account and no profile.

Changes to this page

If what the app does changes, this page changes with it and the date at the top moves. We will not quietly widen what we do and leave the old text standing.

Who we are

Alketo is made by HOREC GROUP s.r.o., Pri parku 1636/14, 900 26 Slovenský Grob, Slovakia (company ID 53096100), which is the data controller for the purposes of the GDPR.
