Privacy
Kaeru is built privacy-first. We collect a little anonymous usage data to understand which features people use, so we know what to improve — and nothing more. This page explains exactly what that means.
The short version
- Our analytics never collect your code, files, prompts, or the AI's replies.
- If you send us feedback, we only ever receive what you choose to write.
- Usage stats are anonymous — no accounts, no device IDs, no cookies, no fingerprinting.
- In the app, you can turn usage sharing off anytime in Settings.
- We never sell your data, and there are no ads.
The Kaeru app (desktop)
The app uses Aptabase, an open-source, privacy-first analytics tool. It sends anonymous events such as "app started" or which features are opened, plus general info the tool adds automatically (operating system, app version, language). Data is hosted in the EU (Germany).
It does not collect any personal data, and there are no cookies, no persistent user IDs, and no tracking across apps. Your code, files, prompts, and the agent's replies are never sent — only the fact that a feature was used.
You're in control: open Settings → Usage and switch off Share anonymous usage data whenever you like. It stays on during the closed beta so we can learn from real use; when Kaeru launches publicly it will be off by default (opt-in).
This website
On this site we use two privacy-respecting tools to understand how visitors find and read our pages:
- PostHog (PostHog Cloud, US) for anonymous page views and interaction analytics, including heatmaps of where people click. It honours your browser's Do Not Track setting, and we do not create a personal profile for anonymous visitors.
- Cloudflare Web Analytics, a cookieless, aggregate measure of traffic. No cookies, no cross-site tracking.
This is about the website only — it is separate from the app, and neither tool can see anything inside Kaeru.
What we never collect
Your source code, files, folder or file names, prompts, the AI's replies, terminal output, and API keys never leave your machine through our analytics. We don't sell data to anyone, and we don't run ads.
When you send us feedback
Analytics are automatic and anonymous. A bug report is the opposite: nothing is sent until you write it and press send. Our beta and feedback forms are hosted by Tally, a European form service, and the data is stored in Europe.
We receive what you type, plus the app version and operating system when the report is sent from inside Kaeru — that's how we know which build broke. Your email address is optional and only used to reply.
Because a report is written by you, it's the one place your own words could include something private. We ask you not to paste code, file contents, or API keys, and to only attach a screenshot that doesn't show them. We never need any of it to fix a bug.
Your controls
- In the app: Settings → Usage → Share anonymous usage data (turn off anytime).
- On the web: enable Do Not Track in your browser and PostHog will stop collecting analytics for your visit.
Questions
If anything here is unclear, or you'd like your data handled differently, send us a note through this form and leave your email if you'd like a reply. If we make meaningful changes to this policy, we'll update the date at the top of this page.
