Terms of Use

Sojourn · Last updated 27 June 2026

1. Acceptance

These Terms govern your use of Sojourn (the "Service"), operated by Sojourn, a company established in Switzerland at Hammerstrasse 103, 8032 Zurich, Switzerland. By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

2. What Sojourn does

Sojourn helps you record the nights you spend in different countries and regions, track worked days, collect supporting proofs, and generate indicative reports to help you monitor your tax-residence situation. The Service is currently offered as a private beta and may change, break, or be interrupted.

3. Eligibility and account

You must be at least 18 (or the minimum age required in your country) and able to enter a binding contract. You are responsible for complying with the laws that apply to you, including your local tax and reporting obligations. Access may require an invitation during the beta. You are responsible for the accuracy of the data you enter and for keeping your credentials secure. You are responsible for activity under your account.

4. Optional location and inbox features

Nightly location tracking and inbox auto-detection are optional and off until you enable them. By enabling them you authorise Sojourn to record your nightly location (including in the background) and to read the travel and lodging senders you allow, as described in our Privacy Policy. You can disable either feature at any time.

5. Your content

You keep all rights to the data and proofs you provide. You grant us a limited licence to host and process them solely to operate the Service for you. You are responsible for ensuring you have the right to upload any proof or document.

6. Acceptable use

• Do not use the Service unlawfully or to facilitate tax evasion or fraud.
• Do not attempt to disrupt, reverse-engineer, or gain unauthorised access to the Service.
• Do not upload content you have no right to, or that infringes others' rights.

7. Availability and beta status

The Service is provided "as is" and "as available", without warranties of any kind to the fullest extent permitted by law. As a beta, it may contain errors and is not guaranteed to be accurate, complete, secure or uninterrupted.

8. Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental or consequential damages, nor for any tax, penalty, interest, loss or decision arising from your use of, or reliance on, the Service. Nothing in these Terms limits liability that cannot be limited under applicable law.

9. Termination

You may stop using the Service and delete your account at any time from Settings → Account → Delete account. We may suspend or terminate access if you breach these Terms or to protect the Service.

10. Changes to the Service or Terms

We may modify the Service or these Terms. We will post the updated Terms here and update the date above; continued use after changes means you accept them.

11. Apple App Store

If you downloaded the app from the Apple App Store, the following also applies. These Terms are concluded between you and Sojourn only — not with Apple Inc. ("Apple"), and Apple is not responsible for the app or its content. Your licence to use the app is limited to a non-transferable licence to use it on Apple-branded products that you own or control, as permitted by the Usage Rules of the Apple Media Services Terms and Conditions (except that the app may be accessed by other accounts via Family Sharing or volume purchasing, where available).

• Maintenance and support. Sojourn, not Apple, is solely responsible for providing any maintenance and support for the app. Apple has no obligation to furnish any maintenance or support services.
• Warranty. In the event of any failure of the app to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app (if any) to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app; any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are Sojourn's responsibility.
• Product claims. Sojourn, not Apple, is responsible for addressing any claims by you or a third party relating to the app or your possession or use of it, including (i) product-liability claims, (ii) any claim that the app fails to conform to an applicable legal or regulatory requirement, and (iii) claims arising under consumer protection, privacy or similar legislation.
• Intellectual property. In the event of a third-party claim that the app or your possession and use of it infringes that third party's intellectual-property rights, Sojourn, not Apple, is solely responsible for the investigation, defence, settlement and discharge of such claim.
• Legal compliance. You represent and warrant that (i) you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
• Third-party terms. You must comply with any applicable third-party terms of agreement when using the app (for example, your wireless data service agreement).
• Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
