Privacy Policy
Version 1.1 — July 2026 · The honest version: the app sends no telemetry, and the license server stores hashes, not your hardware.
1. The app itself: zero telemetry
Daito's Opti sends no analytics, no usage data, no crash reports — nothing. The app contacts the internet in exactly three user-visible situations: activating/validating/deactivating your license, and when you click the manual update-check button. That's the complete list.
2. What the license system stores
When you activate, our license server stores:
- A SHA-256 hash of your license key — never the key itself in readable form.
- Hashed hardware component identifiers (motherboard, CPU, machine GUID — hashed on your machine; raw serial numbers never leave your PC).
- A short machine hash — the same one shown in the app, so support can identify your slot when you mail us.
- A machine name (your PC's hostname, e.g. "DESKTOP-4F2K") from app version 2.4.2 onward, so you can recognize your own machines when managing slots via support.
- Activation timestamps and audit entries (activations/deactivations with timestamp and the short machine hash).
This exists for one purpose: enforcing your key's machine limit (1 PC; 2 for keys bought before 9 July 2026) and helping you in support tickets. It is not used for profiling, not enriched, not sold, not shared beyond the processors below.
3. Buying through Discord, and your e-mail address
Purchases and support run through our Discord via tickets. In a ticket we see your Discord username and whatever you choose to write there; that conversation lives on Discord's platform under Discord's own privacy policy. This site itself has no checkout and never asks for payment details.
If you share an e-mail address with your purchase (or buy by e-mail instead of Discord), it is stored with your key record so we can find your purchase in support cases, and used for delivering your key and answering support. No newsletter, no marketing, unless you explicitly ask for one someday.
4. Processors we use
- Vercel — hosting of this site and the license API.
- Upstash — database (EU region) holding the license records described above.
- Resend — transactional e-mail delivery (key delivery, login links).
Purchases arranged in our Discord happen on Discord's platform (see section 3); Discord is not a processor of the license records above.
5. Retention
License records live as long as your license is valid, plus a reasonable period for support and fraud prevention. Audit entries are capped (oldest entries are discarded automatically).
6. Your rights (GDPR)
You can request access to, correction of, or erasure of your data: mail us (or open a Discord ticket) and we free your machines' slots and delete your key record and its audit trail. Erasing the record also ends the license — we cannot verify a license we no longer store. You can also complain to the Dutch DPA (Autoriteit Persoonsgegevens) if you believe we handle your data unlawfully.
7. Contact
