Privacy Policy
Last updated: 2 July 2026
ReciproCal is designed so that your calendar data never has to leave your device. This policy explains what that means in practice.
Responsible party
The controller responsible for data processing under the GDPR is:
Andreas HähnelNeukircher Str. 3
74357 Bönnigheim, Germany
Phone: +49 7141 1338333
Email: mail@hpn.io
What we don’t do
We collect nothing. ReciproCal has no user accounts and operates entirely on your device. We do not collect, transmit, store, or have any access to your events, calendars, or personal information.
Calendar access
ReciproCal uses Apple’s EventKit framework to read the calendars you have already configured in your system settings and to write mirrored events according to the rules you create. This access:
- requires your explicit permission through the standard system prompt;
- stays on your device — no event data is ever sent over the network by ReciproCal;
- can be revoked at any time in System Settings.
No third-party accounts
ReciproCal never asks for the credentials of iCloud, Microsoft 365, Google, or any other provider. It only works with the calendars your operating system already syncs.
Analytics and tracking
ReciproCal contains no third-party analytics or advertising SDKs and does not track you across apps or websites. On the App Store, ReciproCal is labelled “Data Not Collected.”
Purchases
Subscriptions and one-time purchases are handled entirely by Apple through the App Store. We never see your payment details.
Website hosting (Cloudflare Pages)
This website is served through Cloudflare Pages (Cloudflare, Inc., USA). When you visit, Cloudflare processes technically necessary connection data (e.g. IP address, timestamp, page requested) to deliver and secure the site. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in a secure, functioning website).
Contact form
The contact form is processed through Formspree (Formspree, Inc., USA). When you submit the form, the data you enter (name, email, message) is transmitted to Formspree and forwarded to us by email so we can answer your request. The legal basis is Art. 6(1)(b) and (f) GDPR. You may also email us directly instead.
Your rights (GDPR)
You have the right to access, rectify, erase, restrict processing of, port, and object to the processing of your data. To exercise these rights, contact the address above. You also have the right to lodge a complaint with a data-protection supervisory authority.
Changes to this policy
We may update this privacy policy to reflect changes in the law or in features. The current version is always available on this page.
