Janolab Studio LLC is the controller of the personal data below. The short version: your images are never stored, and we keep as little as running a free tier and selling passes needs.
Images
An uploaded image is read into the memory of the server function handling your request, traced, and dropped when the answer is sent. It is never written to disk, to a database, to a log or to any third party. The file name is used only to name your download.
What we keep, and for how long
| Data | Why | Kept |
|---|---|---|
| Hashed network address (salted SHA-256), day, keyed fingerprint (HMAC) of each image traced for free | Counting the free tier; the same image is not counted twice | 7 days |
| E-mail, product, amount, provider’s order id | Delivering and recovering the pass, refunds, accounting | 400 days after payment |
| Pass code, quota, status, validity | Checking the pass | Until 30 days after the pass ends |
| Keyed fingerprints of images used on a pass | Not charging the same image twice | 30 days |
| Pre-order: e-mail, chosen product and use | One e-mail when checkout opens | Until that e-mail is sent, or until you ask |
| Launch offer: keyed hash (HMAC) of your e-mail address, never the address itself, and the keyed fingerprint of each image downloaded free | Counting the free launch images per address; the same image is not counted twice | 30 days after each download |
| Launch offer: your answers to the short questionnaire (file usable, would you have paid, machine or software, comment), tied to the image’s keyed fingerprint, without your e-mail | Improving the tracer and setting the price | 12 months |
| Daily counters (traces, pre-orders, sales), without any personal data | The owner’s dashboard | Indefinitely |
Processors
Vercel Inc. (hosting; functions run in Washington, D.C., United States (Vercel iad1)); Supabase Inc. (database, hosted in the European Union); Paddle.com Market Limited (payment, as merchant of record and independent controller of your payment data); Resend Inc., United States (sending our e-mails). Transfers to the United States rely on these providers’ standard contractual clauses.
Launch offer
While the launch offer runs, a full-resolution download can be free against an e-mail address. The address is used only to count the free images: we store a hash of it made with a secret key, from which the address cannot be read back, deleted 30 days after each download. No e-mail is sent to it. The questionnaire after the download is optional; its answers do not contain your e-mail and are deleted after 12 months. Please write no name or address in the comment. To have the hash deleted earlier, write to hello@rasterklar.com from or with the address you used.
No tracking
No advertising, no analytics cookies, no third-party trackers. The only cookie-like storage is your pass code, kept in your browser’s local storage when you paste it, so you do not have to paste it again (clear it from the tracer), and, during the launch offer, the e-mail address you typed, kept in the tab’s session storage until you close it.
Your rights
You can ask for access, correction or deletion of your data, or object to its use, by writing to hello@rasterklar.com. If you are in the EU or UK you may also complain to your data protection authority.
