Privacy Policy

Last updated: June 2026

1. Who we are

Oiko ("we", "us", "our") is a household operations app. If you have questions about this policy, contact us at hello@oikoapp.uk.

2. What data we collect

Account data — your email address, used to sign in via magic link
Profile data — your display name, set during onboarding
Household data — inventory items, meal plans, shopping lists, and activity logs you create or contribute to
Usage data— timestamps of actions (e.g. when an item was added or a meal was logged), used to populate your household's activity feed

We do not collect passwords, advertising identifiers, precise location, or payment information.

3. Why we collect it

Data	Purpose
Email address	Passwordless authentication via magic link
Display name	Identifying you to other household members
Household data	Core app functionality — inventory, meals, shopping
Activity timestamps	Household activity feed

4. How data is stored — Supabase

All data is stored on Supabase, a managed database and authentication platform. Supabase stores data on servers in your selected region. Their privacy policy is available at supabase.com/privacy.

Authentication is handled entirely by Supabase Auth using one-time magic links sent to your email. No password is ever created or stored.

5. Household data and other members

When you join a household, other members of that household can see your email address and display name in the Members menu. They can also see actions attributed to you within the household (e.g. items you added or meals you logged). Household owners can remove members.

We do not share your data with third parties outside of Supabase for infrastructure purposes.

6. Data retention and account deletion

You can delete your account at any time from the app settings. When you delete your account:

Your profile and authentication credentials are permanently deleted
Your contributions to households (items added, meals logged) remain, but are no longer attributed to your account
If you are the sole owner of a household and leave without transferring ownership, the household and all its data will be deleted

7. Cookies and tracking

We do not use advertising cookies or third-party trackers. Supabase Auth uses a session token stored in your browser to keep you logged in.

8. Your rights

You have the right to access, correct, or delete the personal data we hold about you. To make a request, contact us at hello@oikoapp.uk.

9. Changes to this policy

We may update this policy from time to time. Continued use of Oiko after changes are posted constitutes acceptance of the updated policy.
