Privacy policy

How Delia handles your information, in plain English.

Last updated November 12, 2026

Who we are

Delia is an iPhone app made by Arcwell Foundry LLC, a company in the United States. In this policy, “we” means Arcwell Foundry LLC.

Questions about your privacy go to [email protected].

What we collect

  • Your account: your email address and your name.
  • What you ask Delia: your messages and voice requests, and the files, links or photos you share with her.
  • Mail and calendar, only if you connect them: your Google (Gmail and Google Calendar) or Microsoft (Outlook mail and calendar) account.
  • Location, only while the app is open: used for leave-time reminders, for example when to leave for a booking.
  • The beta waitlist: if you join on this website, your email address, when you joined, and whether you confirmed it.

How we use it

We use your information to run Delia for you: to answer your requests, to do the tasks you ask for, and to show you what she plans before she acts. Delia sends a message, books, adds or changes an event, or pays only after you say yes.

We use your waitlist email address only to send your beta invite.

Google user data

If you connect your Google account, Delia reads your Gmail and Google Calendar only to answer and do what you ask. She sends an email, or adds or changes a calendar event, only after you say yes.

  • Google user data is never sold.
  • It is never used for advertising.
  • It is never used to train AI models.
  • People at Arcwell Foundry do not read it, except with your permission, for security purposes such as investigating abuse, or when the law requires it.

Delia’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Microsoft data

If you connect your Microsoft account, the same rules apply to your Outlook mail and calendar: Delia reads them only to answer and do what you ask, sends or changes anything only after you say yes, and the data is never sold, never used for ads, never used to train AI models, and not read by people at Arcwell Foundry except with your permission, for security, or when the law requires it.

AI providers

To answer you, your requests are processed by AI model providers that produce Delia’s answers. The app asks for your consent before any AI use. How AI providers are used.

Payments

When you ask Delia to pay for something, the payment comes from your own Link wallet, and only after you approve it with Face ID. Delia never holds your money.

What we never do

  • No ads.
  • We do not sell your information to anyone.

Your choices and controls

  • See, fix or delete what Delia remembers about you, in the app.
  • Download your data in the app.
  • Delete your account in the app (Settings, Delete account) or by writing to [email protected]. Deleting your account removes your data and disconnects Google and Microsoft.
  • Disconnect Google or Microsoft at any time in the app.
  • To remove your email from the beta waitlist, write to [email protected].

Where your data is kept

This website runs on Cloudflare, and the waitlist is stored in a Cloudflare database. Waitlist confirmation emails are sent through our email provider, Resend. Each person’s data in the app is kept separate from everyone else’s.

Children

Delia is not for anyone under 18. We do not knowingly collect information from children.

Changes

If we change this policy, we update this page and the “Last updated” date. Questions: [email protected].
