Privacy Policy
Hoonslab (“we” or “us”) operates the iOS app SEVO (the “App”) and this website. This policy explains what personal information we process and how. It is a translation of the Korean policy; if they differ, the Korean version prevails.
Summary
- There is no sign-up or login, and the App never asks for your name, email or contact details.
- Your workout records are stored only on your device and are never sent to us. We run no server of our own.
- There are no ads and no usage analytics, and we do not track you.
- The camera is used only when you choose to take a workout photo. Photos you take or pick from your album are stored only on your device and are never sent to us.
- The App does not use your microphone, location, contacts or health data.
- To check whether you have bought the membership, an anonymous identifier and your purchase history are sent to RevenueCat, a purchase management service. Payment details such as card numbers are handled by Apple and never reach us.
1. What we process and why
| Category | Items | Purpose | Where it is stored |
|---|---|---|---|
| Workout records | Exercises, weight, reps or time, workout dates, routines, exercises you add, workout photos you add, app settings | Logging and comparison, showing a photo next to your last one, calendar and exercise trends, the widget and rest timer | Your device (never sent off the device) |
| Membership check | A randomly generated anonymous app user ID, purchase history (product, transaction date), app version, OS version, and technical details such as country and currency | Confirming membership access, restoring purchases, resolving payment errors | RevenueCat, Inc. (United States) |
| Inquiries | Email address, message | Replying and checking errors | Our company email account |
| Website | Access records such as IP address, browser information, date and time | Serving and securing the website | Hosting provider Vercel Inc. (United States) |
The rest reminder is a local notification scheduled on your device; nothing is sent anywhere for it. A backup file you make (including your workout photos) is saved only where you choose and is not passed to us. Workout photos are covered inside the App by default and appear only when you ask to see them.
2. Retention and deletion
- Workout records and photos: kept on your device until you delete them. A photo can be removed on its own from the result screen. You can erase them any time in Settings → Delete all records, and they are removed when you delete the App.
- Membership check information: kept while the service is provided. On request, the anonymous user record is deleted from RevenueCat. Apple’s own purchase records follow Apple’s policy.
- Inquiries: deleted without delay once answered, unless a law requires us to keep them for a set period.
- Website access records: kept for a short time under the hosting provider’s retention policy and then deleted.
3. Sharing with third parties
We do not share your personal information with third parties, except where a law specifically requires it.
4. Processors and international transfer
| Recipient (country) | Items | When and how | Purpose | Retention |
|---|---|---|---|---|
| RevenueCat, Inc. (United States) Privacy Policy | Anonymous app user ID, purchase history, device technical details | Sent over an encrypted connection (HTTPS) when the App launches and when you buy or restore | Checking membership status, restoring purchases | Until the processing contract ends or you ask for deletion |
| Vercel Inc. (United States) Privacy Policy | Website access records | Sent over HTTPS when you visit the website | Hosting and security | Under the hosting provider’s retention policy |
Even if you never buy the membership, the anonymous identifier may be sent when the App launches so that membership status can be checked. Logging and comparison keep working with no network connection.
5. Your rights
You can ask to access, correct, delete, or stop the processing of your personal information at any time by emailing contact@hoonslab.kr. We will act without delay. To find your membership record we may ask for your purchase receipt details. Your workout records exist only on your device, so you can delete them yourself in Settings.
6. Security
- Workout records are stored inside the iOS app sandbox, where other apps cannot reach them.
- Anything sent off the device is encrypted with HTTPS.
- Only one person, the owner, handles personal information.
7. Children
The App does not ask for age or identity and does not knowingly collect personal information from children under 14.
