Privacy
The short version: this site is built to know as little about you as possible. No cookies, no trackers, no ad tech, self-hosted fonts. The product itself is local-first: your footage never reaches us.

What this website processes
- Server logs. The site is served as static files by our hosting provider (Cloudflare Pages). The provider processes technical connection data (IP address, user agent, requested URL) to deliver the page and defend against abuse. Legal basis: legitimate interest (Art. 6(1)(f) GDPR). We do not receive or store these logs.
- Fonts. All fonts are self-hosted on this origin. No request is made to Google Fonts or any third-party font service.
- Cookies & tracking. None. No cookies are set; no analytics run. If privacy-friendly, cookie-free analytics (Plausible, EU-hosted) are added later, this notice will be updated first.
Waitlist
If you join the waitlist, your email address is processed by our newsletter provider Buttondown to send you product updates you asked for. Legal basis: consent (Art. 6(1)(a) GDPR). The list uses double opt-in: you are only added once you confirm the subscription via the link in the confirmation email. You can unsubscribe at any time via the link in every email; unsubscribing deletes you from the list. The address is never sold or shared beyond the provider.
The product (Sisyphos app)
Sisyphos runs on your machine. Your video files, the analysis database, and every measurement stay local. We operate no cloud and receive no footage, no thumbnails, no telemetry.
The optional judgment step sends a small number of keyframe stills and measured signals to Google's Gemini API using your own API key, directly from your machine to Google, under your Google account and Google's data terms. Raw video is never transmitted, and the app enforces this on the file contents, not just file names.
Your rights
You have the right to access, rectification, erasure, restriction of processing, data portability, and objection (Art. 15–21 GDPR), and the right to lodge a complaint with the Austrian Data Protection Authority (dsb.gv.at). Contact for all requests: hello@getsisyphos.com.
