Privacy

Who we are

Eunosa is run by Meagan Victoria Angelucci, a sole proprietor in Canada, who is responsible for your information. Questions or requests: privacy@eunosa.com.

The app: what stays on your device

Your memory, chats, projects, tasks, drafts and progress are kept on your own device, in your browser’s storage, locked with a key that can’t be copied out of the browser. The app has no account, no cookies, no advertising and no visit tracking. Your invite code and settings (such as the theme) are also kept only on your device. The app’s fonts come from Adobe Fonts, which receives a standard web request when a page loads.

What leaves your device to write a reply

Eunosa’s replies are written by a language model from Anthropic, in the United States. For each reply, your device sends a short note through Eunosa’s server to Anthropic: your message, up to five memories that matter to it, up to six recent turns of the chat, and a few facts about what Eunosa keeps. Before a reply is shown, the sentences in which Eunosa talks about itself are checked, and that check sends those sentences and the memories they rely on; for a sentence saying there’s nothing on record, it sends what you have stored, up to a set length. If you ask Eunosa to look over your own draft, the draft is sent. Photos and files you add are sent once with your message to be read, and aren’t kept by Eunosa.

When a question needs something current, Anthropic runs a web search with words its model writes from your message, and Eunosa shows you the words and pages used. Searches are given Canada as a rough location, nothing closer.

Eunosa’s server passes these notes along and keeps none of them. It counts searches and files across everyone each month, as numbers only, to keep within a spending limit. Anthropic handles what it receives under its commercial terms, which don’t let it train its models on it (Anthropic’s privacy policy). Eunosa’s server runs on Vercel, which may process requests in the United States and keeps short-term technical logs, such as IP addresses, to keep the service running and secure.

Using Eunosa on more than one device

If you add a second device, a locked copy of your memory is kept in a database run by Supabase in Canada (Montréal), so your devices stay in step. It is locked on your device before it leaves, and the server can’t open it; neither can Meagan. Your recovery key is shown to you once and never kept by Eunosa. The copy stays until you delete it. When you delete everything, a small note stays behind (a coded id, the coded names of your devices and the time) so your other devices know to delete their copies; it holds nothing you wrote.

Email and calendar, if you connect them

You can connect Gmail and Google Calendar, or Outlook, so Eunosa can help with your email and plans. You sign in on Google’s or Microsoft’s own page, and choose to allow it there. Eunosa asks for the least it needs:

• Gmail: read your email. Eunosa can’t send, delete or change anything in Gmail. When it writes an email for you, it opens it ready in Gmail and you press Send.
• Outlook: read your email and put drafts in your Drafts folder. Eunosa can’t send anything.
• Calendar: read your events, and add or change an event only after you say OK in the app.

The key that lets Eunosa in stays on your device, locked in your browser’s storage. When Eunosa needs it, Eunosa’s server asks Google or Microsoft for a one-hour pass and hands it straight back to your device, keeping nothing. Your email and events go straight from Google or Microsoft to your device, not through Eunosa’s server. When you ask about them, the parts that matter to your question go to Anthropic in the note for that reply, as above, and aren’t kept by Eunosa. Eunosa looks only when you ask, and at most 5 emails a reply. Under the reply it lists each email it used by sender, subject and date (and any events by name and time); that list is kept with the reply like the rest of your chat, never the emails’ own words. Nothing from your email or calendar goes into your memory unless you say yes in the weekly tidy.

We don’t sell this information, use it for advertising, let people read it, or use it to train AI models. Eunosa’s use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

You can disconnect at any time under You in the app; disconnecting Gmail also withdraws the key at Google. You can remove Eunosa from your Google account or Microsoft account at any time, and it stops working straight away. Deleting everything in the app disconnects them on that device too.

Reminders on your phone

If you turn on notifications, Eunosa’s server keeps, for each reminder, only its time, a coded id and the address your browser gave for notifications, never the reminder’s words. The notification says “A reminder from Eunosa” and is delivered by your browser’s own notification service (Apple, Google, Microsoft or Mozilla). The record is deleted once the reminder is sent or cancelled.

What we keep when you join the waitlist

• Your email address
• Which sign-up box you used (top or bottom of the page)
• The date and time you joined, and the wording you agreed to
• When you confirmed, when we last emailed you, and when you unsubscribed, if you do

Nothing else. This site sets no cookies of its own, and Meta’s advertising code only runs if you allow it (see Meta ads). To stop automated spam, the server briefly counts sign-up attempts from each connection; that count lives in memory for up to 10 minutes and is never saved.

How we count visits

To see which pages people read and whether they load quickly, the site uses Vercel Web Analytics and Vercel Speed Insights. They use no cookies and don’t know who you are: each visit is told apart by a code that changes every day, and your IP address isn’t kept. We also count a few steps, such as joining, confirming and unsubscribing, and which sign-up box was used, but never your email address. How Vercel handles this.

Meta ads, only if you allow it

We run ads on Instagram. To learn whether they bring people here, the site can use Meta’s measurement code (the Meta Pixel). It stays off until you choose “Allow” in the box at the foot of the page; before that, nothing is loaded from Meta. If you allow it, Meta sets cookies in your browser and receives which pages you visit here, that you joined the waitlist if you do (never your email address), and technical details such as your IP address and browser. Meta can also use this for its own advertising, under Meta’s privacy policy. Meta is in the United States and Ireland. We remember your choice in this browser only. Change your choice about Meta

What we use it for

First, one email asking you to confirm it was you. Once you confirm, we email you when Eunosa is ready, and now and then about its progress. If you don’t confirm, we don’t email you again. Every email has a one-tap unsubscribe link. We will never sell, rent or share your email for anyone else’s marketing. If we’d like to invite you to take part in a study, we’ll ask you separately first.

Where it’s kept, and for how long

In a database run by Supabase, stored in Canada (Montréal). Only our own server can reach it; the public can’t read the list. We keep your email until you ask us to delete it. If you unsubscribe, we stop emailing you and keep your address marked as unsubscribed. To have it removed completely, email privacy@eunosa.com.

Our emails are sent through Resend, an email service whose servers are in the United States. It receives your address and the email itself only to deliver it, and keeps delivery records (such as whether the email arrived). Resend’s privacy policy.

The site’s fonts come from Adobe Fonts. Loading them sends Adobe a standard web request, which it uses to count page views for font licensing (Adobe’s privacy policy). Like any website, our host may also keep short-term technical logs, such as IP addresses, to keep the site running and secure.

When you email us

Emails you send to hello@eunosa.com or privacy@eunosa.com, and our replies, are kept in our mailbox at Microsoft 365, Microsoft’s email service. We use them only to answer you. We keep them for 2 years after your last message, then delete them; to have them deleted sooner, ask at privacy@eunosa.com. Microsoft’s privacy statement.

Your choices

You can ask what we hold about you, correct it, or have it deleted at any time: email privacy@eunosa.com. We’ll reply within 30 days. If you’re not satisfied, you can contact the Office of the Privacy Commissioner of Canada.
