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
- We never collect your code, files, prompts, or the AI's replies.
- 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.
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.
