We collect several different types of information for various purposes to provide and improve our Service to you.

• To detect, prevent, and address technical issues

Use of AI and Calendar Data

zeitclaim uses artificial intelligence to help you organize and understand your time. We want to be transparent about how your data is used:

• Calendar data is processed solely to provide the Service - analyzing patterns, suggesting time structures, and helping you manage your work
• We do not use your data to train general-purpose AI models
• We do not sell your calendar or personal data
• AI processing happens on secure infrastructure with appropriate safeguards

Legal Basis for Processing Personal Data (GDPR)

If you are from the European Economic Area (EEA), our legal basis for collecting and using personal information depends on the Personal Data we collect and the specific context in which we collect it.

We may process your Personal Data because:

• We need to perform a contract with you
• You have given us permission to do so
• The processing is in our legitimate interests and it is not overridden by your rights
• To comply with the law

Data Retention

We will retain your Personal Data only for as long as is necessary for the purposes set out in this Privacy Policy. We will retain and use your Personal Data to the extent necessary to comply with our legal obligations, resolve disputes, and enforce our legal agreements and policies.

Transfer of Data

Your information, including Personal Data, may be transferred to — and maintained on — computers located outside of your state, province, country, or other governmental jurisdiction where data protection laws may differ.

If you are located outside Germany and choose to provide information to us, please note that we transfer the data, including Personal Data, to Germany and process it there.

We will take all steps reasonably necessary to ensure that your data is treated securely and in accordance with this Privacy Policy.

Disclosure of Data

Business Transaction

If we are involved in a merger, acquisition, or asset sale, your Personal Data may be transferred. We will provide notice before your Personal Data is transferred and becomes subject to a different Privacy Policy.

Legal Requirements

We may disclose your Personal Data in the good faith belief that such action is necessary to:

• Comply with a legal obligation
• Protect and defend the rights or property of us
• Prevent or investigate possible wrongdoing in connection with the Service
• Protect the personal safety of users of the Service or the public
• Protect against legal liability

Security of Data

The security of your data is important to us, but remember that no method of transmission over the Internet or method of electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your Personal Data, we cannot guarantee its absolute security.
