1. No registration
The service has no registration or login. It does not ask for or collect personal data used to create an account, such as name, email, phone number or date of birth.
2. Information collected
Information you enter yourself
- Display name: the name you enter when leaving a message on a card. It does not have to be a real name; a nickname or any text works. It is shown on that card.
- Your content: the card title, sticky note messages, stickers, drawings and the display settings attached to them, such as position, color and font.
Information collected automatically
- Local browser identifier: so that you can edit and delete your own posts, a randomly generated identifier is stored in your browser's local storage. It is a random string that cannot identify a person, and it disappears when you clear browser data.
- Access and usage logs: to improve the service, Google Analytics collects statistics such as pages visited, time on page, device and browser type, and approximate region.
- Advertising data: third-party ad providers may use cookies and similar technologies to serve ads. See section 5.
3. Purposes
- Providing the basic features: creating, viewing, editing and deleting cards
- Keeping a card in sync so that several people can edit it together
- Verifying ownership so that authors can edit and delete their own posts
- Analyzing usage statistics and improving the service
- Serving ads to cover operating costs
4. Retention and deletion
Cards and the posts on them are kept until a user deletes them. The service has no automatic deletion schedule.
The identifier and display name stored in your browser disappear as soon as you clear browser data. Display names already attached to posts remain until those posts are deleted.
5. Cookies and advertising
The service is free, and operating costs are covered by advertising revenue. The following third-party ad providers are used.
- Google AdSense: third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising in Ads Settings, or block third-party vendors' cookies for personalized ads at www.aboutads.info.
- Monetag: may use cookies and advertising identifiers to serve and measure ads. Notification ads are sent only if you grant notification permission in your browser, and the permission can be withdrawn at any time in browser settings.
- Coupang Partners: some product links on the site are Coupang Partners affiliate links, and the service earns a commission on purchases made through them. The service passes no user data in the process; after you follow a link, Coupang's privacy policy applies.
You can refuse cookies in your browser settings, although some features may then not work properly.
6. Processors and third parties
The service does not sell your information. It relies on the infrastructure of the following companies, and information is stored and processed on their servers in the course of operation.
- Supabase: storing and syncing card data
- Vercel: website hosting and deployment
- Google: usage analytics (Google Analytics), advertising (AdSense)
- Monetag: advertising
Except where law enforcement or similar authorities require it through lawful procedures, information is not provided to any other third party.
7. Visibility
Anyone who has the link to a card can view and write on it. There is no password or invitation step, so check who will receive a link before sharing it. We recommend not writing sensitive personal information such as national ID numbers, bank account numbers or contact details.
8. Your rights
You can edit or delete your own posts at any time. If you cannot, for example because you cleared browser data and lost the local identifier, contact us below and we will help to the extent your authorship can be verified.
9. Children
The service is not directed at children under 14 and does not knowingly collect their personal data.
