Frequently asked Questions

How is the amount of 'contacts' counted and calculated?

Only "synced" contacts are counted.


Example 1:  If you have 100 contacts in app A and 100 different contacts in app B with two-way sync, that means 200 contacts are in sync.

Example 2: If you sync 100 contacts from app A (e.g. a CRM) to 10 different apps (e.g. an Outlook mailbox each), 100 x 10 = 1,000 contacts are in sync.

I'm a reseller. Do you have an affiliate program and special prices?

Yes! Here you will find all important information for resellers.


When will I receive an invoice?

Never within your free trial period! If you chose to activate your account,  you will automatically receive an invoice for the next 12 months by email. Due to the annual billing, we even give you one free month!


Can I sync contacts between all my apps?

We are already working on it! Here you can view all supported apps and test the synchronization at any time.


How safe is my data with you?

sync .blue® only synchronizes your data between your apps - no contacts are cached. In addition, we are subject to the strict German data protection guidelines and must comply with the GDPR.
