Privacy Policy

1.What MiniWiki collects

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.

What we receive per sign-in method

• Google, X Your email, plus the name and profile photo Google or X shares.
• Kakao Your email, plus the nickname and profile photo Kakao shares.
• Apple Your email, plus the name Apple shares. If you pick “Hide My Email,” you get a forwarding address Apple creates instead of your real one. We do not store a profile photo. We also keep one marker so we can disconnect from Apple when you later delete your account. We use that marker only at deletion and delete it along with your account.
• LINE The name LINE shares. We receive your LINE email only after LINE grants the email permission, and we do not store your profile photo.
• Email sign-up Your email address and password.

What we receive as you use MiniWiki

• Things you write yourself The posts you write on MiniWiki, photos you upload, basic info (favorite things, what you are into lately, and so on), the name shown on your MiniWiki title and your handle, comments you leave on sections of a friend’s page, direct messages you send to friends, and the records you keep in your Memory, which only you can see. In the basic info you can also type things that identify you, such as your birth date or the neighborhood you live in. What you put there is up to you, and leaving it out changes nothing about using MiniWiki. If a photo contains location data (GPS), we remove it before saving, so where it was taken is never kept.
• What you exchange through Help The questions you send through Help and the replies, any photo you attach yourself, the page you were on, and your browser and screen size info. We also keep when you last opened a conversation. We use it to show you that a new reply arrived, and our admins use it to see whether you have read their reply.
• What you send through the feedback button When you send us your thoughts through the feedback button on the MiniWiki screen, we receive the message, any photo you attach yourself, the page you were on, and your browser and screen size info.
• What you send in an appeal If we hide your page, we receive the appeal you write to explain why it’s okay. We use it only to read and decide again. You cannot attach photos or files.
• Things we receive when you turn on notifications in the app When you turn on notifications in the MiniWiki app, we receive the number that tells us which device to send your notifications to, and which operating system that device runs. The notification delivery service creates this number fresh for each app install, so the number alone cannot tell who you are, and we do not receive your device model or phone number. If you turn on the Memory reminder (a notification at a time you choose asking whether you want to write today), we receive whether it is on, the hour you picked, and the time zone name your device reports (for example Asia/Seoul) so we can work out what “10 p.m. your time” means. That is a region name, not a location or address. The reminder arrives only if you turned it on, and is skipped on days you already wrote.
• What you send when you suggest a category When you ask us to create a category MiniWiki does not have yet, we receive the name you suggested and, if you wrote one, your note on why it is needed. We also keep which page you suggested it from. Only our admins see it, and we use it only to decide whether to create that category.
• 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, plus the kind of device you used that day (phone or PC) and, for phones, which operating system it runs. For devices we keep only those two and the date, never detailed information such as the device model. In share link access logs, and in the records we keep to stop signed-out visitors from searching too often, we do not store the IP address 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. Records that pile up after you sign in carry a random number tied to your account. We do not send your name or email with them, but they are linked together as one person. While you browse MiniWiki signed out, and while you create your first page right after signing up, we also briefly record screen activity (clicks and scrolling) to see where people get stuck. What you write, what you type, and your name are masked and never kept. After you create your first page, we do not record during normal signed-in use or while you work on private pages.

2.What MiniWiki uses your data for

We use what we receive only to show you the service, verify your account, send account-critical notices by email, send the notifications you turned on in the app, 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, MiniWiki admins can see that a page exists and what is on its cover, even for private pages: the page title, the name and handle shown on it, its visibility, whether it is finished, how many pages there are, when it was last edited, and when a share link was created. For private and friends-only pages, the post content, photos, and what you wrote in the basic info are locked away by our permission system, so not even the admins can see them. The same goes for direct messages you send to friends and friend request messages: the admins cannot see them either. In the cases below, however, the admins do review the content. If the person who received a direct message reports it, the admins review only that message’s text to handle the report. If someone reports a comment left on a section, the admins review that comment and who wrote it in order to handle the report (including comments on friends-only pages). And if you appeal after the admins hide a public page, they can see that page’s posts and photos again, but only while they review your appeal. This is still true even if you switch the page to private in the meantime, and once the review ends they cannot see it again. If they hid a private or friends-only page, they do not open its posts and photos even when you appeal: they decide again from what was reported to them or sent through Help, together with the cover information listed above.

Help works differently. A question you send through Help is a conversation addressed to the admins, so they can see the message, any photo you attach, and the replies. We use it to answer you and fix the problem. We also gather part of what you wrote in Help and feedback into a daily internal report, so we can see what keeps tripping people up: we leave out names and handles, mask contact details, have the AI summarize it, and email it to our admins (see “Where my data goes” below, under Anthropic and Resend). We never use it for advertising or hand it to other companies. It is best not to write anything in Help that you would not want the admins to read.

When and how it is sent When you use AI writing help or Memory AI, the exchanged content and the text it refers to are sent over the internet at that moment, when a page is shown in another language, the content being translated is sent the same way, and when you make a story card, that page’s text is sent the same way. Because anyone can read a public page, we send it regularly whenever its content changes to check for anything problematic, such as harassment or bullying, nudity or sexual content, threats or violence, private information, or spam. The AI does the checking, not a person reading through your page one line at a time, and if nothing looks wrong we keep only the time of the check, not the text. Storage and servers are used the whole time you use MiniWiki.

Why we send it AI writing help and Memory AI are features you ask for, so we send what is needed to provide them (that is, to keep our agreement with you for using MiniWiki).

How to refuse If you do not want your data to go to the companies in the table above, you can refuse at any time.

• How Stop using or turn off the feature that company handles. If you do not use AI help or Memory AI, no conversation is sent to Anthropic, and if you turn off “Let AI refer to this” on a Memory record, that record is not sent as a reference. If you turn off app notifications, we stop sending to the companies that deliver them, and the Memory reminder can be turned off separately inside the app. If you do not make a story card, that page’s text is not sent for one. If you do not press the KakaoTalk share button, nothing is sent to Kakao. If you keep your pages private or friends-only, they stay out of the automatic check. For services with no per-person off switch, such as analytics, sign-in, and operations alerts, the only way to refuse is to delete your account. For anything you cannot stop by turning a feature off, email help@mini.wiki.
• Procedure Once you turn a feature off, we stop sending from then on. If you email us, MiniWiki will look into it and reply with how we handled it.
• What happens if you refuse You cannot use the feature that company handles. Without AI help you can still make your MiniWiki by filling an empty page yourself, and you can still write in your Memory yourself. Storage and servers (Supabase, Vercel), however, are essential to the service, so if you refuse those too, you cannot keep using MiniWiki and will need to delete your account.

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 MiniWiki keeps your data

Your Memory, which only you can see We keep the date, title, text, footnotes, and photos of the records you keep in your Memory, along with their “Let AI refer to this” setting and your Memory reminder settings (whether it is on, the hour, and the time zone name). Reminder settings are no longer used once you turn the reminder off, and are deleted with your account when you leave. Text you write in a record is saved automatically as you write. Picking a date and leaving creates an empty record for that date. Only you can view them, regardless of your wiki’s visibility. When you chat with the AI or draft a record in your Memory, we also send Anthropic the date and text of your records from other days that have “Let AI refer to this” turned on, as a reference. When you add to an existing record, we also send that record’s text. When you chat, we also send the basic info, categories, section titles, and part of the section text of your main page. Photos are never sent to AI. MiniWiki does not separately store the raw conversations you have with the AI in your Memory on its servers. We delete the copy of a record’s earlier content without delay once we no longer need it. Copies can remain for a while in the backups we keep for outages. Deleting a record immediately hides it and excludes it from AI reference. You can undo a deletion for a short time right after it; after that, scheduled cleanup removes the record and its photos. If you take a photo out of a record, we delete that photo 24 hours later. From then on, not even you can open it. If you put it back within 24 hours, the photo stays.

• When you leave, we delete everything: your MiniWiki (all pages and photos), your Memory records and photos, your account data, and the edit history of who changed what and when. Once deleted, it cannot be undone. There is one exception, and we spell it out right below.
• One exception: the usage records we keep to see where people get stuck are not deleted when you leave. They stay for up to 7 years under the retention policy of the company we entrust with analytics. What we do delete when you leave is the profile attached to those records (things like how you first found MiniWiki when you signed up). If you want the remaining records deleted too, email us using the address in “Your rights over your data” below.
• Conversations with the AI themselves are used only while generating an answer and are not stored separately on MiniWiki servers. However, when you ask the AI to write something for your page, we save the conversation you have had up to that point along with that request. We keep the request, the results, and usage records until you ask us to delete them or you leave, and when you leave they are deleted along with your MiniWiki.
• Instagram story cards stay on our server for only 10 minutes after we make the image, then they are deleted. We keep only the numbers of the sentences we picked so the same card can be made again quickly, never the text itself. Changing the page’s content, name, or visibility, or deleting the page, removes them immediately.
• 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.
• Only when the automatic check spots something potentially problematic on a public page do we briefly keep the passage it flagged (up to 500 characters), so it is clear which part was caught. We never keep a separate copy of the whole post. Once the admins finish reviewing, we delete that passage right away, and we delete the remaining check record 90 days after the review. For pages where nothing looked problematic we create neither that passage nor a check record, and keep only the time of the check.
• When we hide a public page, we keep a copy of the page as it was at that moment for a short time so we can review an appeal later. Only we can see that copy, and only while an appeal is being reviewed; we delete it as soon as we decide. If no appeal arrives, we delete it after 90 days. If an appeal arrives but the decision takes long, we delete it no later than 90 days after the appeal was sent. If you delete the page, the copy and the appeal go with it. When we hide a private or friends-only page, we do not make that copy at all. We keep the appeal you wrote, because you wrote it, and we delete the note we left about our decision after 90 days.
• Help conversations are deleted along with your account when you leave. You can delete your own messages inside a conversation, in which case the content disappears and only the trace of the deletion remains. When an admin edits a reply, we keep a record of that edit, used only to verify that your question was handled properly. We also delete the thoughts and photos you send through the feedback button when you leave.
• Records we keep to see whether translation worked contain no post content, only an identifier for the page, the language, and whether it succeeded, and they are deleted after 180 days. Because they contain nothing that identifies a person, they may remain for that period even after you delete the page or your account.
• We keep the device number used to send app notifications only while you have notifications turned on. We delete it as soon as you turn notifications off or sign out, and we delete numbers that no longer reach a device, such as when you delete the app, as soon as we notice. When you leave, it is deleted along with your account.
• Category suggestions are deleted along with your account when you leave. The record of how our admins handled a suggestion does keep the suggested category name, but it never says who suggested it.
• If the law requires us to keep certain data, we keep it only for that period and then delete it.
• When we delete something, we make sure it cannot be recovered. Once the retention period ends or there is no longer a reason to hold data, we delete it without delay. Data stored on computers is erased in a way that cannot be brought back, and anything printed on paper is shredded or burned. Copies can remain for a while in the backups we keep for outages, and we use them for nothing else while they are there.

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 have your collected analytics records deleted, contact help@mini.wiki.
• You always decide who sees your page, and every page starts private. You can change the visibility whenever you like, and a page you opened up to public or friends can always be set back to private.
• Friends-only has one exception, for a single photo. Your posts and other photos stay visible to MiniWiki friends only, but the one photo in your main page’s basic info appears to other signed-in people as a round profile picture, so they can recognize you and find friends. People who are not signed in do not see it. If you would rather not, delete that photo or set the page to private.
• Public pages can appear in recommendations inside MiniWiki. Your page may show up where MiniWiki picks pages to show, such as “Browse at random”. Search sites are still blocked. If you would rather not, set the page to friends only or private, or contact help@mini.wiki.

6.How MiniWiki keeps your data safe

We store passwords encrypted so that even MiniWiki cannot see the original, and we record the IPs in share link access logs and signed-out search records only in an unrecognizable form. We block private data from anyone without permission, and even pages set to public are blocked from search engines. The content and photos of private and friends-only pages, direct messages, and friend request messages cannot be seen by the admins either. The admins do see the questions you send through Help, since they have to answer you, and the posts and photos of a page you appealed, since they have to review the appeal (see ‘What MiniWiki uses your data for’ above).

We keep making these efforts, but they may not stop everything, such as illegal acts by others like hacking, or problems caused by not keeping your own password safe. When a problem arises from causes like these, which are not MiniWiki’s fault, it is hard for MiniWiki to take responsibility for it. That said, if we find a problem, we will notify you quickly as the law requires and take the necessary steps.

7.Cookies (small notes kept in your browser)

A cookie is a tiny note that a website leaves in your browser. The next time you come back, your browser shows that note to MiniWiki, and MiniWiki reads it to recognize that it is you again. That note is why you do not have to sign in again every time you move to another page.

These are the notes MiniWiki leaves:

• A note that keeps you signed in So you do not get signed out as you move between pages.
• A note that remembers your language If you read in Korean, we show Korean again next time.
• A note that checks share links To confirm that someone who followed a link is allowed to see that page.
• A note that shows where people get stuck We leave it to group the clicks that came from the same person. This note never holds your name or email. Once you sign in, a random number tied to your account rides along, so what one person did stays linked together. We also use another kind of note that your browser keeps only on your own device, and we put nothing that identifies a person there either.

We never leave the kind of cookie other companies use to follow you around and show you ads. There is exactly one exception: when a Help notice has a video attached, we show that video from YouTube. So opening the notice sends the information needed to connect (your internet address and browser type) to Google, which makes YouTube. We embed it in the mode that leaves no tracking cookies. You can delete these notes or block them entirely in your browser settings at any time. Features that need them, like staying signed in, may then stop working properly.

In the MiniWiki app, instead of cookies the app securely keeps notes on the device: your sign-in, settings such as notifications, language, theme, and translation, and when we last asked you to rate the app. These notes stay on that device and are not sent to MiniWiki’s servers. Only where the app opens a web screen, such as editing a page body or reading this document, do we include the note that keeps you signed in.
