Daylight Calendar

Calendar, tasks, sun and moon — with your existing calendar accounts, no account of its own and no server

Privacy policy

Last updated: 5 September 2026

Daylight Calendar is a calendar and task app. It shows and edits your events and reminders through Apple's calendar system (EventKit). We run no server for this app, there is no account or login, and the app contains no analytics, no advertising and no third-party SDKs. We receive no data from you. Place search goes through Apple Maps (see below).

1. Data controller

We have not appointed a data protection officer or an EU representative because we do not reach the relevant thresholds. Please address all requests to the contact above.

2. What data we process

What we explicitly do not collect

• No account, no name, no e-mail address
• No advertising, no advertising ID, no analytics, no trackers, no third-party SDKs
• No server of our own: events, reminders, location and settings never go to us; the only exception is place search via Apple Maps
• Face ID: the check is done by iOS on the device; the app receives no biometric data

3. Permissions on your device

The app requests only the following permissions. Each of them can be revoked at any time in your device settings; the app remains usable afterwards, with reduced functionality.

• Calendars (full access) — Show, add and edit events. Without permission the app shows only sun and moon times.
• Reminders (full access) — Show tasks next to events, add and complete them.
• Location (while using the app) — Optional: sun and moon times for your place. Without permission you can choose a place by name.
• Contacts — Optional, only for birthday ages.
• Face ID — Optional: app lock.

4. Legal bases

We process personal data under the Swiss Federal Act on Data Protection (revFADP). Where the GDPR applies, we rely on:

• Performance of a contract (Art. 6(1)(b) GDPR) — everything needed for the app to deliver the function you requested.
• Legitimate interests (Art. 6(1)(f) GDPR) — secure and stable operation, abuse prevention, troubleshooting.
• Consent (Art. 6(1)(a) GDPR) — for anything you actively enable in this app: access to calendars and reminders (processed on the device and in your own accounts) and location (optional; calculated on the device). Consent can be withdrawn at any time with effect for the future by revoking the permission in your system settings.
• Legal obligation (Art. 6(1)(c) GDPR) — in particular commercial and tax retention duties for payments.

5. Recipients and third parties

We do not sell data and do not disclose it for advertising purposes. Data is disclosed only to the following parties, and only where required for operation:

Authorities and courts receive data only where we are legally obliged to provide it.

Transfers abroad

Some of the recipients listed above process data outside Switzerland and the EEA, in particular in the United States. We base such transfers on the European Commission’s Standard Contractual Clauses with the Swiss adaptations recognised by the FDPIC and, where applicable, on the EU-US Data Privacy Framework. We will provide information on the safeguards in place on request.

6. Retention and deletion

We store nothing because we run no server for this app. Events and reminders stay in your calendar accounts; settings, calendar groups and the chosen place live on the device and are deleted when you remove the app.

Step-by-step instructions are available at Delete data.

7. Children and young people

This app is not directed at children. We do not knowingly collect personal data from children under 16. If we learn that such data has been submitted without parental consent, we delete it without delay.

8. Data security

Wherever the app transmits data at all, connections are encrypted via HTTPS/TLS. On the server side we use access restrictions, tenant separation and regular backups. Nobody can, however, guarantee absolute security for data transmission over the internet.

9. Your rights

• Access to the personal data we process
• Rectification of inaccurate data
• Erasure or destruction of your data
• Restriction of and objection to processing
• Receiving or porting your data in a common format
• Withdrawal of consent with effect for the future

An informal message to info@babala.ch or a call to 076 792 63 50. We normally respond within 30 days. To verify your identity we may request suitable proof. You may also lodge a complaint with a supervisory authority (Switzerland: FDPIC; EU: your competent authority).

10. Changes to this policy

We may adapt this policy when the app or the legal framework changes. The version published on this page, with the date shown above, is the applicable one. We announce material changes inside the app.
