Privacy notice
Whatever DeeZen processes on your device is private. Nothing more is promised. When a task needs more than your device can do, it leaves by one of the routes named below — and each route says exactly what it carries.
1. What stays on your device
DeeZen is built local-first. These live on your computer, not on our servers:
- your conversations and session history;
- your memories, corrections and learned preferences;
- the files you work on and the project context Dee reads;
- your scheduled tasks and saved settings;
- your API keys for the providers you connect.
We do not run an account system for the core product. We do not receive your conversations, your files, or your keys.
2. What leaves your device — every route, named
Nothing below is claimed to be private. Each row is a route the product can take, what it carries, and who receives it.
| Route | What it carries | Who receives it |
|---|---|---|
| Your AI provider (you chose it; your key) |
The request you made — text, and images if you attached them — sent with your own API key. | That provider, under their privacy terms. We never see this traffic or your key. |
voice.deezen.ai |
The text Dee is asked to speak. This service is text-to-speech only; it has no speech-to-text, so microphone audio is not sent to it. | A server we run, which returns audio. |
lang.deezen.ai |
The text of a turn when translation is used — for a non-English question, or to answer in your language. | A translation server we run, which returns the translated text. |
brain.deezen.ai |
The text of a turn that uses the shared native-language brain. | A shared server we run. Currently offline (it returns HTTP 530), so no turn reaches it today. |
phone.deezen.ai |
Messages between your phone and your own computer when you pair a phone. Each message is signed with a per-phone secret; the relay can delay a message but cannot forge or replay it. | The relay we run, which carries the message to your computer. |
| Paddle (payments) |
Purchase details when you buy a subscription or credits. Paddle is the merchant of record and the controller of that data. | Paddle. We receive subscription status and credit balance — not your card details. |
link.deezen.ai |
Downloads of model files and release manifests. | A storage service we run. These requests carry no personal content. |
| Public data lookups (only when a question needs them) |
The search terms or identifiers needed to answer — for example a company name or a fact to check. | Wikipedia, Wikidata, SEC EDGAR, the IMF, the World Bank, Britannica, DuckDuckGo or Bing, under their own terms. |
| Social publishing (only accounts you connect) |
The post you wrote, and any media you attached. | Bluesky, Mastodon, LinkedIn, Meta or TikTok — whichever you connected. |
3. What we do not do
- The desktop app contains no analytics or telemetry client; its logs stay on your device.
- This website sets no advertising or analytics cookies. The pricing page loads Paddle's checkout script, and Paddle may set cookies when you open checkout.
- We do not sell personal information, and we do not build advertising profiles.
- We do not ask for an account, a phone number, or a date of birth to use the core product.
4. Hosting and logs
This website and its downloads are served through Cloudflare. Cloudflare processes standard request data — such as IP address and user agent — to deliver the site and protect it from abuse. Our own servers keep short-lived operational logs needed to run the services above; we do not use them to build profiles of what you ask Dee.
5. Your controls
- Keys: stored on your device. Remove one in Settings, and revoke it with the provider at any time.
- Conversations and memories: stored locally; you can delete a session or a memory, and uninstalling removes the local store.
- Off-device routes: the cloud tiers and shared services are used only for the turns that need them, and the product labels them where they occur.
- Support email: write to us to ask what we hold about you, or to have it deleted.
6. Retention
Local data stays on your device until you delete it. Purchase records held by Paddle are kept as long as tax and accounting law requires. Support correspondence is kept only while the issue is open and for a reasonable period afterwards.
7. Children
DeeZen is for people aged 16 and over. It is not directed at children, and we do not knowingly collect information from anyone under 16.
8. Changes
If this notice changes, the new version is published here with a new effective date. Material changes will be described in the product's release notes.
