Privacy policy

Effective October 10, 2026

Noteko is an Android app for notes to yourself, which makes reminders, events and to-dos from them on your phone. This policy explains what the app does with your information. In short: what you write and say stays on your phone. We don't collect it, we can't see it, and the app has no account, no analytics, no advertising and no tracking.

What stays on your phone

Everything you put into Noteko is stored only in the app's private storage on your phone:

• your messages, and the reminders, events, to-dos, notes and bookmarks made from them;
• photos, files and voice notes you attach;
• the app's settings;
• the search index the app builds so you can find what you saved.

None of this is sent to us or to anyone else, and none of it goes to Android's cloud backup. The only thing the app lets Android back up to your Google account is the date your free trial started, so reinstalling the app doesn't start the trial again.

The AI runs on your phone

Noteko uses small AI models that run on the phone itself: one that understands your requests, and one that helps search what you saved. Your requests and your data are never sent to a server to be processed.

Voice

When you tap the microphone, Noteko records your voice only while it's listening, and passes the sound to your phone's own on-device speech recognition, which works without the internet. Noteko asks only for the on-device recognizer, never for one that may send audio to a server. If your phone has none, or you prefer it, you can download Noteko's own speech recognition, which also runs entirely on the phone; it never uses the cloud. The recording isn't kept. Spoken replies use your phone's own text-to-speech, with a voice installed on the phone.

On many Android phones the on-device speech recognition is provided by Google's system services. Their handling of on-device recognition is described in Google's own policies.

What the app downloads

Noteko uses the internet only to download things it needs, never to send your data:

• AI models: after you install the app, it downloads its models over Wi-Fi from our model server (models.notekoapp.com, hosted on Cloudflare). When you open the app's model screen, it also checks our model server for newer versions. So that the models go only to Noteko as installed from Google Play, the app first asks Google Play for an integrity check (Google Play Integrity), which Google Play services answers using information about your device and the app's installation, as it does for purchases; our server receives only Google's verdict, never anything you wrote or said.
• Noteko's own speech recognition, only if you choose to download it, from the same model server.
• Speech recognition language: if your phone doesn't have on-device English (US) speech recognition, the phone offers to download it from its own provider.

As with any download, these servers see your device's IP address and the file requested, and may keep it in short-lived technical logs. No account, identifier or personal information is sent with these requests.

Buying Noteko

After the free trial, you buy Noteko through Google Play. Google Play handles the payment, under Google's privacy policy; Noteko never sees your card or payment details. To know whether you've bought it, the app asks the Google Play Store app on your phone, not a server of ours. Google Play gives us the usual order records for a sale (such as the order number, the date, the price, and the country or postal area), which we use only for accounting, taxes and refunds.

The waitlist on this website

If you join the waitlist at notekoapp.com, we keep the email address you enter and the time you joined, in a database at Cloudflare, which hosts the website. We use it only to email you when Noteko is on Google Play and, if you're one of the first 100 on the list, to send you the code that unlocks Noteko for free. We don't send newsletters or marketing to it, and we don't share or sell it. We don't keep your IP address with it; to stop abuse, Cloudflare counts how often one IP address submits the form, for a minute at most. The website sets no cookies and has no analytics.

To be taken off the list, write to hello@notekoapp.com. We delete the list once Noteko is on Google Play and those emails have gone out.

When you contact us

If you report a reply or write to us, your email app sends us what you choose to send: for a report, the reply, the request it answered and the app and Android versions, which the app fills in for you to review first. We use it only to look into the report or to answer you.

Permissions

• Microphone: to hear voice requests while you're using voice.
• Notifications, alarms and reminders, running in the background: so reminders arrive on time, even when the app is closed and after the phone restarts.
• Calendar: only if you choose to add an event to your phone's calendar, so the app can create and update that copy.
• Internet and network state: to download the AI models over Wi-Fi.

You can change any of these in Android's settings at any time.

Deleting your data

You can delete any message or item in the app. Uninstalling Noteko deletes all of its data from your phone, including the downloaded models. Because we never receive your data, there is nothing for us to delete on our side, apart from your waitlist address if you joined.

Children

Noteko isn't directed at children under 13, and we don't knowingly collect information from anyone, of any age.

Changes

If this policy changes, the new version will be posted here with a new effective date.
