Privacy Policy
Effective November 2, 2026Sweetndata Inc. ("we") operates the VISTEND service (the "Service"). This policy explains what personal information we collect, why, and how we use, keep and delete it.
1. Information we collect
| Category | Information | How we collect it |
|---|---|---|
| Sign-up & sign-in | Email address, name and profile photo (provided by Google when you sign in with Google), account ID | Sign-up and sign-in screens |
| Wait list & inquiries | Name, email address / (optional) company or team, phone, message | Wait list and contact forms |
| Video generation | Uploaded source videos, job settings (clip, output size), generated results | Provided by you in the workspace |
| Automatically | Access logs, IP address, browser and device information, usage records | Generated as you use the Service |
We don't offer online payment yet. When we do, payment details will be handled directly by a payment provider; we will not store card numbers or other payment credentials.
2. How we use it
- To identify members, keep you signed in and prevent misuse
- To generate video extensions (outpainting), deliver results and keep your job history
- To tell wait list members when the Service opens
- To receive and answer inquiries and orders, and send quotes and timelines
- To improve quality, fix errors and keep the Service secure
3. How long we keep it
We delete personal information without delay once its purpose is fulfilled. Retention periods:
- Account information: until you close your account
- Wait list and inquiry information: one year after the launch notice or after your inquiry is handled, or until you ask us to delete it
- Uploaded source videos and results: deleted within 30 days after the result link expires (7 days after generation)
- Access logs: 3 months (Protection of Communications Secrets Act)
Once paid services start, we will keep contract and withdrawal records and payment and delivery records for 5 years, and consumer complaint and dispute records for 3 years, as required by the Korean E-Commerce Act.
4. Sharing with third parties
We do not provide your personal information to third parties unless you consent or the law requires it.
5. Processors and international transfer
We use the following processors to run the Service, and some processing happens outside Korea. We supervise them to make sure your information is handled safely.
| Processor | Task | Country | Information |
|---|---|---|---|
| Vercel Inc. | Website hosting, handling inquiries | United States | Access logs, inquiry and wait list information |
| Supabase Inc. | Authentication, job data storage | To be announced | Account information, job settings and history |
| Google LLC | Sign in with Google | United States | Email address, name, profile photo |
| Video generation provider (to be announced) | Generating video extensions | To be announced | Source videos, job settings |
Transfers happen over the network when you use the Service, and retention follows section 3. If you don't want your information transferred abroad, you can choose not to sign up or generate videos, or close your account — but you won't be able to use the Service.
6. Deletion
When the retention period ends or the purpose is fulfilled, we delete personal information without delay — electronic files in a way that can't be recovered, and paper records by shredding or incineration. Information we must keep by law is stored separately.
7. Your rights
You can ask to access, correct, delete or stop processing your personal information, and withdraw your consent, at any time.
Email vistend.ai@sweetndata.com and we'll act on it without delay. A legal representative or someone you authorize can also make the request.
8. Cookies and local storage
The Service stores the following in your browser so it can work. We do not use tracking tools for advertising or behavioral analytics.
- Language preference (vt_lang)
- Sign-in token to keep you signed in (vt_auth)
- Screen state (whether the alert card is closed, where to return after sign-in)
You can clear this in your browser settings; doing so signs you out and resets your language.
9. Security
- Encryption in transit (HTTPS) and least-privilege access
- Limited lifetime for sign-in tokens, and signed result links that expire after 7 days
- Access logging for systems that handle personal information
10. Children
The Service does not accept sign-ups from children under 14.
