Note: This is a translation for convenience only. In case of discrepancies between the German and the English version, the German version shall prevail.
By accessing or using the SuperSync service ("Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you may not access or use the Service.
SuperSync is a data synchronization service designed to work with the Super Productivity application. It allows users to synchronize their task data across multiple devices. The Service is provided in its currently available version ("as available"). The Provider may further develop, modify, restrict, or discontinue the Service at any time.
To use the Service, you must register for an account. You agree to provide accurate, current, and complete information during the registration process and to update such information to keep it accurate, current, and complete.
You are responsible for safeguarding the password and access tokens that you use to access the Service and for any activities or actions under your account.
Your use of the Service is also governed by our Privacy Policy. Data transmission is encrypted via TLS/SSL. By default, data is stored without end-to-end encryption.
You may optionally enable End-to-End Encryption (E2EE). If enabled, your encryption keys are generated and managed locally by you. Warning: We have no access to these keys and cannot recover encrypted data if you lose your key. Loss of your encryption key results in permanent data loss.
Backups are performed on a best-effort basis. You are obligated to create regular local backup copies of your data.
You agree:
If you violate these Terms and the Provider is held liable by third parties as a result, you shall indemnify the Provider against all related claims.
The Service is currently provided free of charge. However, we reserve the right to introduce fees for the Service in the future. We will provide notice of any such changes before they become effective.
You may delete your account at any time via the app settings, thereby terminating the contract.
For free services, we may terminate the contractual relationship with a notice period of two (2) weeks. We may terminate or suspend your account immediately without notice only for good cause (e.g., violation of these Terms, illegal activities).
For paid services, the notice periods stated in the order process apply.
We may amend these Terms if necessary to adapt to technical developments, changes in legal frameworks, new functions, security requirements, or business models.
Amendments will be communicated to you at least six (6) weeks before they take effect. The notification will include your right to object and your right to terminate the contract. If you do not object within the notice period, the amendments are deemed accepted.
The Provider is liable without limitation in cases of intent, gross negligence, and culpable injury to life, body, or health.
In cases of slight negligence, the Provider is only liable for the breach of essential contractual obligations. In these cases, liability is limited to the foreseeable damage typical for the contract.
Data Loss: Liability for data loss is limited to the effort that would have been required for recovery assuming proper, reasonable, and regular data backup by you. If you have not created sufficient backups, liability is excluded insofar as the damage would have been avoidable through backups.
E2EE Data: The Provider is not liable for data loss, data corruption, or inaccessibility attributable to key loss, incorrect key management by you, or use of the optional E2EE function.
If you are a consumer and conclude a paid contract, you are entitled to a statutory right of withdrawal of 14 days. Details are regulated in the separate cancellation policy provided during the order process.
The law of the Federal Republic of Germany applies, excluding the UN Sales Convention (CISG). If you are a merchant, a legal entity under public law, or a special fund under public law, Leipzig is the exclusive place of jurisdiction. Statutory places of jurisdiction apply to consumers.

The Provider is not obligated and not willing to participate in dispute resolution proceedings before a consumer arbitration board.
