Privacy Policy
Everything that applies to Blurt is here. The general part below covers the website and all apps.
Effective from September 28, 2026
This document is translated from the Czech version for your convenience. In case of any discrepancy between language versions, the Czech version is binding.
In short
- Recordings and notes stay on your device and in your iCloud. They never reach our servers.
- Transcription and sorting into categories happen on the iPhone, without cloud AI.
- The app has no account and no advertising identifiers. It only sends anonymous daily counts of screens and the Premium offer.
- Apple verifies the subscription directly; only Apple sees payment details.
- Delete notes in the app and iCloud data in the iPhone's Settings.
This summary is for quick orientation. The full text below is what applies.
What the app does
Blurt is a voice notes app. You record a note on Apple Watch, your iPhone transcribes it and files it into a category (shopping, work, ideas…) on its own. The core principle: the content of your notes is processed only by your devices, not by our servers.
What stays on your device and in your iCloud
- Recordings, transcripts, categories and their keywords
- App settings (transcription language, recording clean-up, interests picked during onboarding)
- Subscription status, shared between iPhone and Apple Watch
Data is stored on your device and, if iCloud is on, in your private iCloud storage (Apple CloudKit) so it syncs between iPhone and Apple Watch. I have no access to that storage and I am not the controller of that data. Recordings travel between Apple Watch and iPhone directly via Apple Watch Connectivity.
Speech transcription
Transcription runs on your iPhone using Apple's speech recognition (Speech framework). Neither recordings nor transcripts are sent to my server for transcription. iOS downloads the Czech or Slovak language model from Apple on first use. Categorisation and detecting a due date ("tomorrow at 12:00") or priority ("urgent") happen on the device using rules, with no cloud AI.
Reminders
When you send notes to Reminders, manually or automatically for a chosen category, the app writes them into the Reminders app on your device, including the detected due date, alert and priority. This needs your permission in iOS, which you can revoke any time in iPhone Settings. Reminders are then handled by Apple under its own terms.
Subscription
Blurt Premium is purchased through Apple In-App Purchase. Only Apple sees payment details. The app verifies purchases directly with Apple (StoreKit), with no other third-party service and no user account.
Anonymous usage statistics
To improve the app, it sends daily counts: how often each screen was shown, on which screen the app went to the background, and how often the Blurt Premium offer was shown and for which feature it ended in a purchase. Only these totals are sent, without any user or device identifier and without any content of your notes or recordings. They are stored in Firestore (Google/Firebase, region europe-west3) and cannot be linked to a specific person.
Survey and support
The survey in Settings is optional. Answers are stored in Firestore (Google/Firebase, region europe-west3) with only the app version and language, without any user or device identifier and without an e-mail. If you choose to be contacted, the process in section 4 of the general part applies: the support chat opens with your answers pre-filled and the e-mail you enter yourself.
The in-app support chat works as described in section 4 of the general part. The app never attaches note content or recordings automatically; only what you type into the chat is sent.
What the app doesn't collect
- Note content or recordings on my servers
- Location
- Contacts, calendar or photos
- Advertising identifiers (IDFA) or statistics linked to you (the counts in section 6 are anonymous totals)
- Your name or e-mail, unless you enter it in the support chat
Retention and deletion
You can delete notes directly in the app. The app can delete recording audio automatically after a period you choose (Settings → Recordings); the note text stays. Delete iCloud data in iPhone Settings → [your name] → iCloud. Survey answers and support tickets are kept for at most 24 months; you can ask for earlier deletion under section 7 of the general part.
Contact
Reach out via Support or straight from the app (Settings → Support).
General part (applies to the website and all apps)
Data controller
The data controller is Vojtěch Landa, a private individual, contact: vojtajess@gmail.com. Neologos Development is not a legal entity or a registered business — it's the name under which Vojtěch Landa, as a private individual, develops and runs neologos.dev and the apps listed below.
What this page covers
This privacy policy is shared across neologos.dev, vejce.neologos.dev, and the apps Blackout, Eco, WorthIt, Blurt, Migrelog, and Limi. Each app also has its own section below, since it processes different data depending on what it does — the general part applies to all of them, and the app section adds to it.
Website traffic
neologos.dev collects basic, aggregate traffic statistics (visit counts, pages visited, approximate geographic area from IP address) via Vercel Analytics and, if enabled, PostHog. This data only exists to show whether the site is being used at all — it isn't sold, isn't shared with ad networks, and isn't linked to a name or email unless you provide one yourself (e.g. via the support chat).
Support chat and tickets
The Support section on the website and the support chat inside the apps let you report a bug, suggest an app improvement, ask about legal information or ask a general question. Chat messages are saved as a ticket in Firestore (Google/Firebase, see point 5). Messages in every category are answered by an AI assistant through the Anthropic (Claude) API. Anthropic acts as a processor: it handles the message, including the earlier conversation, only to produce a reply and does not use it to train models.
When you report a bug directly from an app, a technical app log (error messages and app state) is attached to the ticket so the problem can be traced. An email or name is stored only if you type it into the form yourself — it is never collected automatically.
Blackout, WorthIt, Blurt and Migrelog also include a short, optional in-app survey. At the end we ask whether you'd like us to get back to you. If you choose "No", your answers are sent without an e-mail address or any contact detail, i.e. anonymously. If you choose "Yes", your answers are sent the same way and the app opens the support chat with your answers pre-filled in the message and the e-mail address you enter yourself. The message and e-mail are then stored as a ticket as described in this section, and the e-mail is used only to reply to your feedback. The survey record itself stays without an e-mail address.
Shared infrastructure
The website and apps run on Firebase/Google Cloud (Firestore, Cloud Functions, Cloud Messaging) — the servers for the apps and site are set to a European region (europe-west3) wherever Firebase allows it. Google acts as a processor there under its own privacy policy (firebase.google.com/support/privacy).
Push notifications (where an app offers them) use the Apple Push Notification service — Apple only needs an anonymous device token for this, not personal data.
Advertising and cookies
The /brief page (Brief → Prompt) is funded by ads through Google AdSense so it can stay free. No ad script or third-party cookie loads until you consent in the cookie banner at the bottom of the page.
Once you consent, Google and its ad partners may set cookies to measure and personalize ads under their own policies (policies.google.com/privacy). You can manage ad personalization or opt out at adssettings.google.com.
You can withdraw consent at any time by clearing this domain's cookies in your browser — the banner will show up again.
Your rights
Under GDPR, you have the right to:
- access your data
- correct inaccurate data
- erasure ("the right to be forgotten")
- restrict processing
- data portability
- object to processing
- withdraw consent at any time, where processing was based on it
- lodge a complaint with the Office for Personal Data Protection (uoou.gov.cz)
You can exercise any of these rights simply — write to vojtajess@gmail.com or via Support (category "Legal information").
What to expect from me: I'll reply no later than 30 days after receiving the request — either sending, correcting, or deleting the data right away, or explaining why (and on what grounds) that isn't possible. For a more complex request this deadline can be extended once by another two months, which I'll tell you about within the first 30 days. To verify identity I may ask for extra information (e.g. the email or nickname used in the app), so the data doesn't end up with someone else under your name.
Data retention
Tickets and incidents are kept for as long as needed to resolve the request, plus a reasonable period after for traceability (typically up to 24 months), then deleted. Data stored directly in the apps (see the app sections below) follows each app's own rules — most of it can be deleted immediately right in the app.
A conversation with the assistant where you leave no email is kept on the server only as a hidden draft, so it can still be handed to a person if you add an email. Nobody reads it, and it is deleted automatically after 7 days.
Changes to this policy
This policy may change as the site and apps evolve. The current version is always on this page; the date of the last change is shown in the header.
