The short version
- Zetro is an AI. Your messages go to Anthropic’s models so he can reply.
- He remembers things you tell him. You can see, correct and switch off that memory.
- Your chats, memory and apps are private unless you share an app, publish one, or use Wingman.
- No ads, no ad tracking, no selling your data.
- You can download everything, or delete your account, from inside the app.
Who we are
Zetro One (“Zetro”, “the app”) is made and run by [Operator's legal name], an individual developer based in [Country of residence] (“we”, “us”). We decide how your information is used, so we are responsible for it.
Questions about privacy: support@zetro1.com. Post: [Postal address for legal notices].
What Zetro is
Zetro is an AI. He is not a person, and nobody reads along while you talk to him. His personality, moods and the life he tells you about are written by AI models. When you need a tool, he can build you a small app (a “mini-app”) that keeps its own data.
To do that, your messages and some of what Zetro knows about you are sent to an AI provider, Anthropic, which writes his replies. Everything else in this policy follows from that.
What we collect
We collect only what the app needs to work. Most of it is things you give Zetro yourself.
| What | Details | Where it comes from |
|---|---|---|
| Your account | A random account ID. If you sign in, the email address and name your sign-in provider shares (Google, or email and password). Passwords are handled by Firebase Authentication; we never see them. | Created when you first open the app; sign-in is optional |
| Your display name | The name other people see in shared apps, the marketplace and Wingman. It starts as your first name from your sign-in, or the first part of your email address, and you can change it once. | Your sign-in, or what you choose |
| Conversations | Your messages, photos you send in the chat, Zetro’s replies, a running summary of older conversation, and his mood and story with you. | You and Zetro |
| Memory | People, plans, preferences and other things you have shared, noted from your chats so Zetro remembers them. Health and relationship details are marked sensitive. Money and identity-document details are not kept unless you ask. | Your chats, or what you add yourself in “What Zetro remembers” |
| Settings | Quiet hours, whether Zetro may ask how things went, GIFs and memes, and whether romance appears in his life (18+). | You |
| Mini-apps | The apps Zetro builds for you, their earlier versions, what you wrote about why you want them, and what you store in them: records, photos, recordings and files. | You and Zetro |
| Reminders and alarms | What you asked to be reminded of, and when. | You |
| Your phone | A notification token, an install ID, the platform (iOS or Android) and your time zone, so Zetro can text you at sensible hours. | The app |
| Wingman (optional) | The profile you write, the people you ask your Wingman to find, the conversations between Wingmen, summaries, your messages to people you are introduced to, blocks and reports. | You, and other Wingman users |
| Usage and safety | How many AI requests you make each day, by feature, with their size and estimated cost; which days you used the app; whether each notification was delivered and tapped; and counters that stop overuse, stored with your account ID and network address scrambled (hashed). | Our servers |
| Crash reports | When the app crashes: the error, the device model, the operating system and the app version. | Firebase Crashlytics |
| App integrity checks | A token from Google Play Integrity or Apple App Attest showing that a request came from the real app. | Your phone's operating system |
We don’t use advertising IDs, analytics or ad-tracking tools, and the app doesn’t ask to track you across other companies’ apps.
How we use it
- To run Zetro: to write his replies, remember what matters to you, text you first, build and run your mini-apps, keep reminders, and keep your data in step across your phones.
- To keep him safe and kind: the app looks for words that suggest a hard moment, so Zetro can be gentler. If you tell him you are under 18, romance stays out of his life.
- To protect the service: to confirm requests come from the real app, limit how much any one account or address can use, and fix crashes.
- To understand cost and reliability: to see what each feature costs to run and whether notifications arrive.
- To answer you when you contact us.
AI processing
Zetro’s replies, the apps he builds, and the AI features inside your apps are made by models from Anthropic (Claude). To write a reply, our server sends Anthropic your recent messages, a summary of older ones, relevant memories and settings, and any photo you shared. When a mini-app uses AI, it sends what that app needs, such as a photo you took in it.
Anthropic processes this on our behalf under its commercial terms, which do not allow it to train its models on this data. We don’t use your conversations to train AI models either.
AI can be wrong. Zetro may misremember, misunderstand, or say something that isn’t true. You can correct what he remembers at any time.
Memory you can see and change
After a reply, Zetro notes what seems worth remembering from your newest messages. You can see everything he has noted in Settings → What Zetro remembers, and you can add, correct or forget any of it.
Switch off Remember things from our chats there, and he keeps only what you ask him to keep.
Texts and notifications
Zetro texts first, through push notifications, more often in your first days and less after that. We send these through Firebase Cloud Messaging using your phone’s notification token.
You decide how much of this you get. Set quiet hours in What Zetro remembers, tell Zetro in the chat that you want him to stop texting first, or turn notifications off for the app in your phone’s settings.
What other people can see
Your chats, memory and apps are private. Other people see something of yours only in these cases:
- Shared apps. If you share an app with someone, the people in it see the data in that app and your display name.
- The marketplace. If you publish an app, other Zetro users can see its listing and your display name, and can make their own copy. Their copies stay theirs if you delete yours.
- Wingman. Your profile is hidden until you choose to be found, and you choose which fields to share. Experience and location are off by default. Your Wingman can use only what you share. It talks with other people’s Wingmen through our servers and AI, and you are introduced to someone only if you both say yes.
Camera, microphone, location and photos
The app asks for each permission only when a feature needs it, and you can say no or change your mind in your phone’s settings.
- Camera and photos: to send a picture in the chat or use one in a mini-app. Photos you send are stored with your account.
- Microphone and speech recognition: to record a voice note in a mini-app, or to dictate. Dictation happens on your phone; if your phone can’t recognise speech on the device, dictation is refused rather than sent elsewhere.
- Location: only when a mini-app you use asks for it, for example for local weather. It is stored only if that app saves it.
- Scanning: reading barcodes, text and image labels in mini-apps happens on your phone, with Google’s ML Kit.
- Notifications and alarms: to deliver Zetro’s texts, reminders and alarms.
Connected accounts
If you connect Google Calendar, Zetro can read your calendar events (read-only access) to help you plan. The access tokens are stored encrypted. Disconnecting, or deleting your account, revokes our access at Google and deletes the tokens.
Who processes your data
We don’t sell your personal information or share it for advertising. We use these services to run Zetro:
| Provider | What they do | What they receive |
|---|---|---|
| Google Firebase | Sign-in, the database, file storage, push notifications, crash reports and app integrity checks | Everything stored with your account, your notification token, crash details |
| Anthropic | The AI models behind Zetro and your mini-apps | The conversation, memory and content described above |
| Render | Hosts our server | Requests between the app and our server, and server logs |
| GIPHY | GIFs in the chat, if Share GIFs is on | A short search phrase Zetro picks. Your phone loads the GIF from GIPHY |
| Google (Sign-In, Maps) | Signing in with Google; maps inside mini-apps | What you use them for |
| Open data services | Only when a mini-app asks: Open-Meteo, OpenWeatherMap, Open Food Facts, exchangerate.host, Wikipedia and GitHub | Your phone contacts them directly with what the app asks for, such as a place for the weather |
As the operator, we can technically reach stored data through these services. We look at your content only to give you support you asked for, to fix a problem, or when the law requires it. Our cost and operations dashboard shows account emails, activity, cost and notification delivery, not your messages or memories.
We may disclose information if the law requires it, to protect someone from serious harm, or as part of a sale or transfer of Zetro, in which case this policy continues to apply to it.
How long we keep it
| Information | How long |
|---|---|
| Your account, chats, memory, apps, files, settings, reminders and Wingman data | Until you delete them, or your account |
| Notification delivery records | 30 days |
| Overuse counters (scrambled) | Until their time window ends |
| Usage and cost records, and the days you were active | [period, or deleted with your account] |
| Server logs | [log retention period] |
| Crash reports | [crash report retention] |
| Backups | [backup practice and period] |
Deleting your account removes your chats, memory, apps, files, settings, devices and reminders; ends the shared apps you started and leaves the ones you joined; takes your listings off the marketplace; and removes your Wingman profile, searches and matches, including from the other people in them. Copies of your published apps that other people made stay theirs.
Your choices and rights
- See and download your data: Settings → Your account → Download your data gives you every chat, app, record, memory and setting as one file.
- Correct it: change what Zetro remembers in What Zetro remembers.
- Delete it: forget single memories, delete apps, or delete your whole account. See Delete your account.
- Say no: turn off automatic memory, GIFs and memes; keep your Wingman profile hidden; turn off notifications; or refuse a permission.
Depending on where you live, you may also have the right to object to or restrict how we use your information, and to complain to a regulator. In the UK that is the Information Commissioner’s Office (ico.org.uk); in Canada, the Office of the Privacy Commissioner (priv.gc.ca). To use any of these rights, email support@zetro1.com. We may need to confirm the request comes from the account’s owner.
Where UK or EU law applies, we rely on: our contract with you, to provide Zetro; our legitimate interests, to keep it secure, limit abuse and understand cost; and your consent, for device permissions and optional features, which you can withdraw at any time.
Security
Data travels encrypted between the app, our server and our providers. Every request needs your sign-in, and each person can read only their own data. Connected-account tokens are encrypted again before they are stored. No system is perfectly secure; if a breach affects you, we will tell you as the law requires.
Age
Zetro is not meant for anyone under [minimum age]. The app does not ask your age when you start. If you tell Zetro you are under 18, romance stays out of his life. If we learn that someone under the minimum age is using Zetro, we will delete their account.
Where your data is processed
Our providers process data in [countries or regions], which may be outside the country where you live. Where the law requires it, we rely on the providers’ standard contractual protections for these transfers.
Changes to this policy
When we change this policy, we will update the effective date above. If a change affects how your information is used in a meaningful way, we will tell you in the app before it takes effect.
