Privacy Policy

Version 2026-10-21.4

This policy explains how Syncy ("we", "us") handles personal data in Syncy, an appointment reminder service for businesses of any kind.

Privacy contact: info@syn.cy

1. Our two roles

1.1 Processor for your customers' data

Each business decides why and how its customers' data is used, so the business is the controller. We process that data only on the business's instructions, as its processor, under our Data Processing Agreement. If you received a reminder from a business, contact that business to see, correct or delete your data; we help the business answer.

1.2 Controller for business accounts

We are the controller for the data of the business staff who use Syncy and for the website, as described below.

2. Data we process

2.1 For businesses (as processor)
2.2 About business staff (as controller)
2.3 Website and app

Standard server logs (time, request, technical errors), kept for 30 days. No analytics or advertising cookies: see section 8.

2.4 Google user data

When you sign in with Google, we receive your name and email address. When you connect a Google Calendar, Syncy uses that access only to send appointment reminders:

We do not use Google user data for advertising, sell it, or use it to train AI models. No person reads it except to give support you asked for, for security, or where the law requires it. Syncy's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

3. Why we process it (legal bases)

Appointment reminders are service messages about a booked appointment. They are never used for marketing.

4. Sub-processors

We use these providers to run Syncy. We give businesses 30 days' notice before adding or replacing one.

5. International transfers

Our database and servers are in the EU (Paris). Where a provider above handles data outside the EU, the transfer is covered by the safeguard listed for it.

6. How long we keep data

7. Security

If a breach affects a business's data, we tell the business within 24 hours of becoming aware of it.

8. Cookies and browser storage

We use only what is needed for the service to work: short-lived cookies while a business connects its Google Calendar, and the sign-in session in your browser's storage. We use no analytics or advertising cookies, so we ask for no cookie consent.

9. Your rights

You can ask for access to, correction or deletion of your data, ask us to restrict or stop processing it, receive it in a portable format, and object to processing based on legitimate interest.

You can complain to the data protection authority of the EU country where you live or work, or where you think your data was misused (Art. 77 GDPR). For example:

10. Changes

We publish every change here with a new version number. Business admins are asked to accept material changes in the app.
