Voisto — Privacy Policy

Last updated: 5 September 2026

Voisto is a voice-first to-do app that organizes your tasks into an Eisenhower matrix. This policy explains, in plain language, what data the app touches and what it does with it.

Short version

Your audio never leaves your iPhone. Speech is transcribed on-device using Apple's Speech Recognition framework.
Only the transcribed text of a task (for example "Call Peter tomorrow") is sent to Google Gemini through a Cloudflare Worker to classify it into a quadrant and parse deadlines. Nothing else.
Tasks are stored locally on your iPhone in a JSON file. Voisto has no accounts, no cloud sync, no analytics, and no advertising.
You can turn AI classification off in Settings, and you can erase all data with one tap.

Data we access on your device

Microphone — only while you press and hold the record button. Audio is processed by Apple Speech Recognition on-device.
Speech Recognition — Apple's on-device Russian model turns audio into text. Voisto never sees or stores the audio itself.
Notifications — local notifications only, scheduled for task deadlines you set.

Data we send off your device

Task text is sent to a Cloudflare Worker (voisto-proxy.krylova.workers.dev), which forwards it to Google Gemini for classification and deadline parsing. The Cloudflare Worker does not log the text.
See Google's privacy policy for how Gemini handles the text.
You can disable this in Settings → AI Task Recognition. With AI off, dictated text is stored locally as a plain task with no cloud round-trip.

Data we do not collect

No analytics, no tracking, no ad IDs.
No contacts, no location, no photos.
No accounts — there is nothing to sign into.

Third parties

Apple — on-device Speech Recognition (audio never leaves the device).
Google Gemini — text-only classification of your tasks.
Cloudflare — infrastructure that proxies the classification request.

Data retention and deletion

All tasks are stored in a local file inside the app's sandbox on your iPhone. Uninstalling the app deletes everything. Inside the app, Settings → Erase all tasks removes every task instantly.
