Privacy Policy
Last updated: April 2026
This Privacy Policy describes how Ace and Zeros ("we", "us", "our") handles information in relation to the CalenDeus WordPress plugin and this website (calendeus.com).
1. What CalenDeus Is
CalenDeus is a self-hosted WordPress plugin. It runs entirely on your own WordPress installation. We do not operate any central server that stores booking data from our customers' websites. Appointment data entered by your visitors stays on your server.
2. Data Collected by This Website
When you visit this website (calendeus.com), we may collect:
- Usage analytics — pages visited, referrer URL, browser type, and approximate geographic region. This data is collected in aggregate and is not linked to individuals.
- Support form submissions — if you submit a message through our support page, we collect your name, email address, and the content of your message. This is used solely to respond to your enquiry.
- Purchase information — when you purchase a Pro licence, payment is processed by Freemius. We receive your email address and order details to deliver your licence key and provide support. We never see or store your payment card details.
3. Data Collected by the CalenDeus Plugin (on your site)
When your website visitors use the booking form, the following information may be stored in your WordPress database:
- First name, last name
- Email address
- Phone number
- Date of birth
- Gender (optional field)
- Appointment date and time
- Booking notes
- GDPR consent timestamp (when consent field is enabled)
You are the data controller for this information. As a WordPress site operator, you are responsible for informing your visitors about the data you collect, your legal basis for processing it, and providing mechanisms to exercise their rights (access, deletion, portability) under applicable privacy laws such as GDPR.
4. Third-Party Services
Freemius
Licence management and payment processing is handled by Freemius. When you purchase a Pro licence, Freemius collects your name, email address, and payment information. Their privacy practices are governed by the Freemius Privacy Policy.
Google Calendar API
If you (as a site owner) configure Google Calendar sync, the plugin communicates with Google's API using credentials you provide. Google's data practices are governed by the Google Privacy Policy. CalenDeus only requests the minimum Calendar API scopes necessary for sync functionality.
CalDAV Providers
If you configure CalDAV sync (Outlook, iCloud, Nextcloud, etc.), CalenDeus communicates with the URL you provide using the credentials you supply. We have no visibility into this connection.
5. Cookies
This website uses minimal cookies for session management and analytics. We do not use advertising or tracking cookies. We do not use cookie-based remarketing.
The CalenDeus plugin itself does not set cookies on your visitors' browsers.
6. Data Retention
Support enquiries submitted via our contact form are retained for up to 24 months and then deleted, unless a longer retention period is required by applicable law.
Purchase records are retained as long as your licence is active and for up to 7 years thereafter for accounting and legal compliance.
For data stored on your WordPress installation, retention is at your discretion and subject to your own privacy policy obligations.
7. Your Rights
Depending on your jurisdiction, you may have the right to:
- Access the personal data we hold about you
- Request correction of inaccurate data
- Request deletion of your data ("right to be forgotten")
- Object to or restrict certain processing
- Data portability
To exercise any of these rights, contact us via our support page.
8. Security
We take reasonable technical and organisational measures to protect information we hold. However, no internet transmission is completely secure. We recommend that you also ensure your WordPress installation is kept up to date and secured appropriately.
9. Children's Privacy
CalenDeus and this website are not directed at children under 16. We do not knowingly collect personal data from children. If you believe a child has submitted data to us, please contact us and we will delete it promptly.
10. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
11. Contact
If you have questions or concerns about this Privacy Policy or how we handle data, please reach out via our support page.
