2. Overview of Data Processing
This website is a purely informational landing page for the macOS app Kajuto. We do not collect, process, or store any personal data from visitors to this website.
About the app itself: for AI scoring, Kajuto transmits project context (README, package manifest, git-log summary) to an AI endpoint that you configure (default: Claude Code by Anthropic through your own subscription via claude -p; alternatively OpenAI-compatible or DeepSeek via jcode), and accesses the GitHub API through the gh CLI with your own login. Only when you start it does the app fetch links you share, sync Zurufe from the iPhone and Watch app through your own private iCloud database, and send a report you submit through “Feedback…” to TesterPayKit. The iPhone and Watch app works the same way: callouts travel through your own private iCloud database, which we cannot read. Only when you send “Report a Bug…” does your text go to TesterPayKit, with device model, system version, language and app version. There is no session, no usage data and no device identifier in it, and without that button the app has no contact with us. All scores, finds, and embeddings stay local on your Mac; the app collects no telemetry and has no accounts. Details in the data flow.
3. What Data We Collect
None. This website contains no contact form, no newsletter signup, and no login area. No personal data is collected.
When accessing this website, technical connection data (IP address, timestamp, browser type) is processed by the hosting provider. This is technically necessary for providing the website.
4. Purpose of Processing
The only processing is carried out by the hosting provider for the technical provision of the website. No further data processing takes place.
5. Legal Basis
The processing of technical connection data is based on Art. 6 Abs. 1 lit. f GDPR (legitimate interest). The legitimate interest lies in the technically error-free provision of the website.
6. Third-Party Providers and Hosting
This website is hosted on Cloudflare Pages. Cloudflare processes technical connection data for delivering the website. For more information, see the Cloudflare Privacy Policy.
Buying a license: sales run through Lemon Squeezy (Lemon Squeezy LLC, USA) as merchant of record. At checkout, Lemon Squeezy processes your email address, billing and payment data under its own privacy policy. Lemon Squeezy notifies us of the order (including name, email address, country, amount); we use only the email address and purchase time for the license and do not store the order data ourselves (Art. 6(1)(b) GDPR, performance of a contract).
License email: a Cloudflare Worker signs your license from that email address and purchase time and sends it to you via Resend (Resend, Inc., USA). We keep no copy of the license; the app checks it offline.

- Access (Art. 15)
- Rectification (Art. 16)
- Erasure (Art. 17)
- Restriction of processing (Art. 18)
