Privacy Policy

Last updated: 10 November 2026

This policy explains, plainly, what the Dayo app and this website collect, why, where it’s kept, and how to delete it.

1. Who provides Dayo

The Dayo app and dayo.ink are provided by [Name], an independent developer in Saudi Arabia (“we”). For anything about your data: support@dayo.ink.

2. What we keep on our servers

Dayo’s server and its database keep very little:

• An account id that links your account to your Clerk sign-in.
• A Nabta AI usage record for each message: the date, the model used, token counts and the request status. We don’t store message text. It’s used for the message limit and to track cost.
• Your subscription status (product and expiry date), as sent by RevenueCat.
• A fingerprint of deleted accounts: when an account is deleted we keep a one-way hash of its id, so a deleted account isn’t recreated by mistake. It contains nothing personal.

3. Services we use

• Clerk (clerk.com): sign-in. It handles your email address and sign-in sessions. You sign in with a one-time code sent to your email; there’s no password.
• Vercel and Supabase: host Dayo’s server and its database (Postgres), which hold what’s listed in section 2.
• Anthropic (Claude): powers Nabta AI, only through Dayo’s server; the app never talks to Anthropic directly. Details in section 4.
• RevenueCat (revenuecat.com): manages subscriptions. Your customer id there is your Clerk account id, and it receives purchase and renewal information from Apple.
• Apple: payment is handled by the App Store. We never see your card details.

4. Nabta AI

Nabta is opt-in: nothing is sent to her until you accept her consent screen, and you can turn her off anytime in Settings → Nabta AI.

When you message Nabta, your message goes through Dayo’s server to Anthropic so she can answer, along with:

• The conversation text (up to the last 20 messages).
• Your task list: titles, times, repeats, start and end dates, times per day, whether each is done today, and whether it locks apps (a yes/no only).
• Context about your day: today’s date, your time zone, the app’s language, your address form, wake and bed times, workdays, how busy your days are, your reminder style, and whether app locking is set up (yes/no).

We don’t send your name, or which apps you lock. Anthropic doesn’t use this data to train its models.

Your chat history is stored only on your iPhone, excluded from backups, and can be deleted anytime from the chat menu or Settings. Nabta is an AI and can make mistakes.

5. What stays on your device

• App locking (Screen Time): the apps, categories and websites you pick from Apple’s list are stored on your device as opaque tokens we can’t read, and are never sent to us or anyone else. We don’t know which apps you chose or how you use your phone. They may be included in your own device backups, depending on your settings.
• Reminders are local notifications scheduled by your device. We have no push server.
• The widget and Siri use the tasks stored on your device.
• Your tasks, check-offs, settings and onboarding answers are currently stored only on your device. Our server is ready to sync them in the future; if we turn syncing on, we’ll update this policy first.

6. Where data is processed

Dayo’s server and database are in Japan (Tokyo). Clerk, Anthropic and RevenueCat are US companies, and data they receive may be processed there.

7. Keeping and deleting data

• We keep your account id, Nabta usage record and subscription status for as long as your account exists.
• Deleting your account: in the app, go to Settings → Delete account. This permanently deletes your RevenueCat customer record, everything on Dayo’s servers, and your Clerk sign-in. Data on your phone stays until you delete the app.
• Deleting your account doesn’t cancel your Apple subscription. Cancel it in iPhone Settings → your name → Subscriptions.
• Our hosting provider may keep short-lived technical logs for operations and security.

8. Age

Dayo is for people aged 13 and over; anyone under 18 needs a parent’s or guardian’s consent. We don’t knowingly collect data from children under 13, and if we learn of it, we delete it.

9. Your rights

You can ask to access, correct or delete your data, and withdraw your consent (for example by turning Nabta off), under the laws that apply in Saudi Arabia, including the Personal Data Protection Law. Requests: support@dayo.ink.

10. This website

dayo.ink uses no cookies and no analytics or tracking tools, and it loads no fonts or files from other companies. Our hosting provider (Vercel) processes technical data such as your IP address to serve and protect the site. Download links carry a tag that shows us, in Apple’s App Store statistics, which button was used; there’s no tracking tool on the site.

11. Changes and contact

We publish any update to this policy on this page, with the date it was last updated. Questions: support@dayo.ink.

If the Arabic and English versions differ, the Arabic version applies.
