1.What we collect
When you sign in, we receive your email address. We use it to confirm that you are really you, and to contact you when your account truly needs it, such as a password reset. However, if you did not agree to share your email or the permission is not available yet, as with Kakao or LINE, you can still sign up without an email.
- If you sign in with Google, we receive your email plus the name and profile photo Google shares.
- If you sign in with Kakao, we receive your email plus the nickname and profile photo Kakao shares.
- If you sign in with LINE, we receive the name LINE shares. We receive your LINE email only after LINE grants the email permission, and we do not store your profile photo.
- If you sign in with X, we receive your email plus the name and profile photo X shares.
- If you sign up with email, we receive your email address and password.
- Things you write yourself We receive the posts you write on MiniWiki, basic info (name, favorite things, and so on), photos you upload, your display name and handle, comments you leave on sections of a friend’s page, direct messages you send to friends, and feedback you send to MiniWiki (the message, any photo you attach yourself, the page you were on, and your browser and screen size info). If a photo contains location data (GPS), we remove it before saving, so where it was taken is never kept.
- Things created while you use the service We receive your language setting, sign-in method, friendships, friend request messages, likes you press, records of mentioning friends in your posts, records of reporting or blocking someone, page visit history, share link view history, and the requests you send to the AI along with the results, usage, and progress.
- Things that accumulate automatically Usage and access logs. We do not store the IP address in share link access logs as-is: we transform it into an unrecognizable form and keep only a part that cannot identify it exactly.
- Analytics data To see where people get stuck, we receive usage data such as when you viewed or clicked a page and which theme you picked. We do not receive post content, AI conversations, or what you wrote in the basic info. While you browse MiniWiki signed out, we also briefly record screen activity (clicks and scrolling) to see where people get stuck. Names, post content, and typed values are masked and never kept. We do not record during normal signed-in use or while you work on private pages.
🔒 We never collect these at all

We never even built the fields to receive them.
2.What we use it for
We use what we receive only to show you the service, verify your account, send account-critical notices by email, display the MiniWiki you made, help the AI write, and stop abuse. We never sell it to other companies or hand it over for advertising.
To stop abuse and run the service well, the MiniWiki operations team can see whether a page exists, along with its name, count, and so on, even for private pages. We never look at the post content, photos, or what you wrote in the basic info.
3.AI writing help and where your data goes
AI writing help and overseas servers
When you write together with the AI or ask the AI for a draft, we send the exchanged content to the servers of Anthropic, the maker of Claude, so the AI can respond. When someone who uses another language opens a page, we also send that page’s content to the same Anthropic servers to translate it. We save the finished translation with the page and reuse it, so the next reader does not have to wait. Only people who can view the original page can see the translation. To run the service we also use Supabase for data storage, Vercel for servers, and Sentry to find and fix errors. These companies’ servers are located overseas, in Singapore, the United States, and elsewhere.

When and how it is sent When you use AI writing help, the exchanged content is sent over the internet at that moment, and when a page is shown in another language, the content being translated is sent the same way. Storage and servers are used the whole time you use MiniWiki.
If you would rather not If you do not want the AI’s overseas processing, simply do not use the AI help. You can still make your MiniWiki by filling an empty page yourself. KakaoTalk sharing sends nothing to Kakao unless you press the share button. Storage and servers (Supabase, Vercel), however, are essential to the service, so they are used the whole time you use MiniWiki.
By company policy, Anthropic does not use what it receives to train AI models. MiniWiki uses that content to create your page (your posts).
4.How long we keep it
- When you leave, we delete everything: your MiniWiki (all pages and photos), your account data, and the edit history of who changed what and when. Once deleted, it cannot be undone.
- Conversations with the AI themselves are used only while generating an answer and are not stored separately on MiniWiki servers. Requests sent to the AI, the results, and usage records are kept until you delete them or leave, and when you leave they are deleted along with your MiniWiki.
- Page translations are deleted along with the original page when you delete it or leave, and once you edit the content, the old translation is no longer used.
- If the law requires us to keep certain data, we keep it only for that period and then delete it.
5.Your rights over your data
- You can view and edit your info (name, handle) and everything you wrote directly inside MiniWiki.
- You can delete the pages you made, and to stop using MiniWiki you can delete your account in account settings. Leaving also deletes your AI requests, results, and usage records.
- To delete only your AI request and result records, or to ask us to stop using your data, contact help@mini.wiki.
- To turn off analytics collection, contact the same email. An in-app toggle is still in the works and will arrive in a future update.
- You always decide who sees your page, and every page starts private.
6.We keep it safe
We store passwords encrypted so that even MiniWiki cannot see the original, and we record share link access IPs only in an unrecognizable form. We block private data from anyone without permission, and even pages set to public are blocked from search engines.
7.Cookies
We use only the cookies needed to keep you signed in, remember your language, and verify share links. We never use ad-tracking cookies. For analytics we use an identifier cookie and browser local storage to group the same person’s clicks, but we never send person-identifying data like emails or real names to analytics. You can block or delete cookies in your browser settings, though some features like staying signed in may stop working properly.
8.Privacy team
MiniWiki does its best to keep your personal data from leaking or being violated. If you have questions or concerns about your data, email us below. That said, MiniWiki cannot take responsibility for problems caused by your own mistakes or in places MiniWiki does not manage.
- In charge: Operations team
- Email: help@mini.wiki
9.Children under 14
Only people aged 14 or older can use MiniWiki. We check that you are 14 or older when you sign up.
