3. What stays on your device
Edit PDF, Image to PDF, Multiple Images to PDF, Image to Text and the Citation Generator run entirely in your browser. The files you open in them, and the text you type, are not uploaded to our servers.
4. What we do not do
- We do not read, scan or analyse the contents of your documents.
- We do not sell your data or use it for advertising.
- We do not access your Google Drive, Gmail or other Google files. Sign-in requests only your name, email and profile picture.
- We do not send your files to third-party text-recognition or conversion services.
5. Service providers
| Provider | Role | Data involved |

| Supabase | Database and private file storage | Account and history records; conversion files while they exist |
| Vercel | Web hosting | Standard request logs such as IP address and time |
6. Who can see your data
You can see your own profile and activity. Administrators can see user accounts, their usage history and conversion file names for support and operations. Administrators cannot open your files. Access to the database and storage is limited to the service itself.
7. Security
Sign-in is verified on the server and limited to university email domains. Uploaded files are stored privately and are only available to the account that uploaded them. Connections use HTTPS. No system is perfectly secure, so please do not upload documents you are not allowed to process.
8. Your choices and rights
You can delete a conversion at any time from the conversion screen, and expired files are removed automatically. You may ask us to access, correct or delete the data held about your account, and to stop processing it, by contacting us through swannhtet.com. This policy is written with the principles of the Thailand Personal Data Protection Act B.E. 2562 (2019) in mind.

We may update this page when the service changes. The date at the top shows the latest version.
