Privacy Policy

1. What we keep

• Account: your email address, display name, password (stored only as a secure hash by our sign-in provider), and when you accepted our terms.
• Signing in with Google or Kakao (if you choose to): from Google, your name, email address, profile picture link and Google account ID; from Kakao, your Kakao nickname, profile picture link, email address and Kakao account ID. They are kept with your sign-in record and updated each time you sign in that way. Your display name starts as that name or nickname, and you can change it. We never receive your Google or Kakao password, and we do not show the profile pictures.
• Level test: your score and level, your learning goal, interests and most comfortable language, and the matching preferences you choose (preferred lesson times with your time zone, preferred tutor gender and age group). If you take the test without an account, the result stays in your browser until you sign up, and is then saved to your account.
• Email after the level test (guests only, if you choose): your email, optional name, level and goal, and when you agreed to be contacted.
• Bookings: which tutor, lesson or free consultation, the time, and whether it is requested, confirmed or cancelled (and why, if the tutor declined it or did not answer in time).
• After lessons: the lesson reports and level reports your tutor writes (summary, feedback, homework, goals, skill scores), your tutor's private progress notes about you, the reviews you write, and the tutor the GwenchanaClass team matches you with.
• Reports of lesson options: when you report a lesson option, we store which option, your account and the time. Only the GwenchanaClass team (admins) can see who reported an option: not the tutor and not other learners. A person can send at most 20 reports in any 24 hours. A report is kept until the option or your account is deleted.
• Notifications: the updates shown under Notifications (booking requests, confirmations, cancellations, reports, reviews, answers and decisions from the GwenchanaClass team), and whether each one and each lesson reminder was emailed to you.
• Saved tutors: the tutors you save with the heart, and when you saved each one (up to 100). Only you can see the list: tutors, other learners and the GwenchanaClass team do not, no one is told that you saved a tutor, and we do not count saves or use them to rank tutors.
• Learning goal (if you set one in My lessons): what you want to learn Korean for, the level you want to reach and how many lessons a week you aim for. It is kept until you clear it or delete your account. Only you can read it: tutors, other learners and the GwenchanaClass team (admins included) cannot. My lessons uses it, with your confirmed lessons, to show your progress in the current week.
• Email settings: which of three kinds of notification email you want (booking and lesson emails, lesson reports and feedback, other messages from GwenchanaClass). If you never change them, nothing is stored and all three are on.
• Messages to the GwenchanaClass team: your name, email, topic, message and our answer.
• Invitations: your personal invite code, and the code you signed up with, if any.
• Tutor applications: name, email, university, major (optional), languages, motivation, documents you attach (such as certificates or transcripts), and the review status.
• Tutor profiles (tutors only): name, Korean name, university, major (optional), headline, bio, experience, teaching style, photo, intro video, gender and age group if given, lesson topics, levels, interests, languages, price, weekly availability, the dates you mark as days off (Korea time, up to 90 upcoming ones), and the lesson link you save for your learners.
• Tutor records (tutors only): whether and when you marked the first-lesson guide as read, and how your lesson requests ended (confirmed, declined, not answered in time, withdrawn). Your cancelled and no-show lessons are kept as part of your lessons.
• Technical data: our providers keep standard server logs, such as IP address, browser and request time, for security and operations. [Confirm log retention.]

We do not take payments, so we hold no card or bank details.

2. Why we use it

• to run your account and keep you logged in,
• to suggest tutors and a study plan based on your level test and preferences,
• to manage lesson bookings, lesson links and lesson reports between you and your tutor, and the days a tutor does not teach,
• to keep the tutors you saved and the learning goal you set for you, and to show your progress towards the goal,
• to show notices from the GwenchanaClass team (notices are written by the GwenchanaClass team; they hold nothing about you),
• to review tutor applications and show tutor profiles and reviews,
• to answer your messages, and to write to you about your level and goal if you left your email after the level test,
• to count who signed up through an invite link,
• to send the emails an account needs: sign-up confirmation and password reset, and, once we switch them on, the same updates you see under Notifications and a reminder about an hour before each lesson, except the kinds you switched off in your email settings. We send no marketing emails.

3. Who can see it

• A tutor you send a lesson request to sees your display name, the lesson time, the level and goal from your latest level test, and the reports and notes they wrote. Only you and your tutor see your lesson reports; tutor notes are visible to the tutor only.
• The days off of a published tutor are public (learners need them to see which times are open); a tutor's days off are not shown for a profile that is not published, except to that tutor and the GwenchanaClass team. Your saved tutors, your learning goal and your email settings are seen by you alone: not by tutors and not by the GwenchanaClass team.
• The GwenchanaClass team (admins) can see whether and when a tutor marked the first-lesson guide as read, and for each tutor how many lesson requests came in, were confirmed, declined or ran out unanswered. Other tutors and learners cannot. A tutor sees their own cancelled and no-show lessons for the last 60 days, with the learner's display name and the option the learner chose, and nothing else about the learner.
• Only learners with a confirmed lesson get that tutor's lesson link. Other learners never see your bookings or requests. They only see which times are already taken.
• Reviews are public, shown with your first name. Published tutor profiles, including photos and intro videos, are public, and those files have public web addresses. A tutor's university and major are public in the same way: the profile shows them, the comparison shows the major, and the tutor list lets learners filter by them (it is built from the universities and majors of all published tutors). They are deleted from the profile when a tutor deletes their account.
• The GwenchanaClass team (admins) can see account names and roles, level test results and preferences, bookings, lesson reports, reviews (including hidden ones), who reported which lesson option, messages, emails guests left after the level test, invite statistics, tutor applications with their documents, and all tutor profiles, to match learners, review tutors and run the service.
• Service providers: Supabase stores our database, sign-ins and files, and sends account emails. [Web hosting provider] serves the website. Once notification emails are switched on, an email delivery provider ([Email provider, e.g. Resend]) sends them and receives your email address and the content of each email. [List any other providers.]
• Sign-in providers: if you sign in with Google or Kakao, they confirm who you are and learn that you use GwenchanaClass. We send them nothing else about you.

We do not sell your data or share it with advertisers.

4. Where it is stored

Your data is stored with Supabase in [hosting region]. [Describe safeguards for international transfers.]

5. Cookies and browser storage

We use cookies only to keep you logged in, and one more ("ykt-consent") that remembers for a year that the account signed in on this browser has accepted our terms, so we do not check again on every page. Your browser's local storage may hold a level test result you took before signing up, an invite code from a link you opened (for 30 days), and small settings such as whether a tutor has read the first-lesson guide. We do not use advertising or analytics trackers.

6. How long we keep it

We keep your data while your account is open. When a tutor deletes their account, some of their records are kept for 30 days more (see 7). An email left after the level test is kept until you ask us to remove it or withdraw your consent. [Retention period for server logs, backups and messages.]

7. Deleting your account

You can delete your account at any time in Account settings. This deletes your login, email, display name, level test results, bookings, saved tutors, learning goal, email settings, the reports of lesson options you sent, lesson reports about you, your tutor's notes about you, messages you sent while signed in, your invite code, tutor applications, and uploaded photos, videos and documents. Reviews you wrote stay for other learners, shown as “Former learner” instead of your name.

If you signed in with Google or Kakao, deleting your GwenchanaClass account does not remove GwenchanaClass from the apps connected to your Google or Kakao account. You can remove it there: in your Google Account under Security (your connections to third-party apps and services), or in your Kakao account settings (연결된 서비스 관리). [Confirm whether GwenchanaClass must also disconnect the account on Kakao's side (Kakao's unlink API) when it is deleted.]

If you are a tutor (or were one), you can no longer log in and your tutor profile disappears from GwenchanaClass at once: it is unpublished, unlinked from your account, and its text, photo, video and lesson link are removed from it (a copy of the text is kept for 30 days, below; the photo and video are deleted). Upcoming lessons and lesson requests waiting for you are cancelled and your learners are told. Your private notes about learners, your days off, the saves other learners made of your profile, uploaded files, tutor applications, the messages you sent to the GwenchanaClass team while logged in and recommendation letter requests that were not issued are deleted at once.

For 30 days after that, the GwenchanaClass team (admins only) keeps a copy of what your profile said, your name, email and account details, and can still see which lessons you taught, the reports you wrote and the recommendation letters GwenchanaClass issued to you (the name, text, date and letter number on them). We keep these to settle your last lessons and to confirm a letter is genuine when someone asks with its number. After 30 days a daily job deletes the copy and the issued letters; from then on we can no longer confirm your letters. The lessons and reports stay in your learners' own lesson history without your name, and an empty profile record stays because they refer to it. [30-day retention and the deletion of issued letters to be confirmed after legal review.]

8. Your rights

You can change your display name, the email address you log in with, and your password in Account settings. After an email change the old address is no longer kept with your account; messages and tutor applications you already sent keep the address written in them and see your bookings in My lessons. To get a copy of your data, or to correct something you cannot change yourself, email support@gwenchanaclass.com. [Rights under applicable law to be completed after legal review.]

9. Children

GwenchanaClass is meant for people aged [minimum age] and older. [Parental consent rules to be completed after legal review.]

10. Changes and contact

We will update this page when what we keep changes, and tell you about important changes before they apply. Questions: support@gwenchanaclass.com. Data protection contact: [Name or role].
