AI Calendar · Last updated: May 2026
AI Calendar ("the App") is developed by Runbiao Peng. This policy explains what information we collect, how we use it, and your rights regarding your data. We have designed the App to collect as little data as possible.
Content you submit for analysis
When you submit a photo, text, or voice recording to extract calendar events,
that content is sent to our secure processing server (Cloudflare Worker) and
forwarded to third-party AI services (Anthropic Claude and OpenAI Whisper) for
analysis. We do not store your photos, text, or voice recordings on any server
after processing is complete. They are discarded immediately once the
extracted events are returned to your device.
Usage counters
The App tracks how many analyses you have used (to enforce free and paid tier
limits). These counters are stored locally on your device and, if you are signed
into iCloud, synced via iCloud Key-Value storage so they persist across your
own devices. This data is never shared with us.
Calendar data
Extracted events are saved directly to your iPhone's Calendar app using Apple's
EventKit framework. This data stays on your device and is governed by Apple's
own privacy policy.
Upload history
A local history of your past submissions (thumbnails and event titles) is stored
on your device only. It is never transmitted to our servers.
The App uses the following third-party services to process your content:
The App offers optional auto-renewable subscriptions (Pro and Business tiers). All billing is handled by Apple through the App Store. We do not have access to your payment details. You can manage or cancel your subscription at any time in iPhone Settings → Apple ID → Subscriptions.
The App is not directed at children under 13. We do not knowingly collect any personal information from children.
All communication between the App and our processing server is encrypted via HTTPS. Content submitted for analysis is processed in-memory and not written to persistent storage on our servers.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated date. Continued use of the App after changes constitutes your acceptance of the updated policy.
