Legal
Terms of Use
The agreement for using Stay180.
Last updated 17 September 2026
Agreement
These Terms of Use (“Terms”) govern access to and use of Stay180 at stay180.app (the “Service”), operated by AI Transform Studio Ltd (registered in England and Wales). By using the Service or buying Stay180 Pro, you agree to these Terms.
These Terms are a practical self-serve product agreement. They are not a substitute for legal advice. For material disputes, have a qualified solicitor in England and Wales review them.
The Service
Stay180 is a planning tool that counts days of presence against the Schengen short-stay 90/180 rule, using stays you enter or import. It can show days used, days remaining, and a last day you can stay based on those stays.
Stay180 is not immigration advice, visa advice, legal advice, or a government service. Border officers and the official EU short-stay calculator are authoritative. You must verify results before you travel.
We may improve, change, or discontinue features with reasonable notice where practicable.
Using Stay180
Stay180 does not require an account. Confirmed stays are stored in this browser on your device. If you clear site data, switch browsers, or use another device, those stays are not there unless you restore a backup you downloaded.
You are responsible for the accuracy and completeness of stays you add or import, including whether a day counts as presence in the Schengen Area.
Acceptable use
You must not use the Service to:
- Violate law, or infringe others’ intellectual property or privacy rights
- Attempt to access another person’s data or circumvent access controls
- Probe, scan, or attack the Service except with our prior written consent
- Upload malware or content that is unlawful, abusive, or harmful
- Misrepresent Stay180 output as official immigration advice or as a government determination
- Resell or white-label the Service except under a separate written agreement
Your data
You retain whatever rights you have in the stays and calendar information you handle in Stay180.
Stays you confirm are saved on your device. We do not upload them to Stay180 servers.
If you connect Google Calendar, Google sign-in and calendar reading happen in your browser. We request read-only calendar access. We do not request Gmail. We do not store your Google login or your calendar on our servers. Closing the tab signs you out of Google for Stay180. Only stays you confirm are saved on this device.
If you drop a calendar file, it is read on this device. It is not uploaded.
If you buy Stay180 Pro, Stripe processes the payment. Card details are handled by Stripe, not stored by us.
Calculator results
Stay180 performs date arithmetic against the Schengen 90/180 rule as we implement it. Results can be wrong if stays are missing, overlapping, mis-dated, or if the rule is applied differently at the border.
You must review results and, where it matters, check the official EU short-stay calculator and a qualified adviser. We do not warrant that a result will be accepted by any authority.
Fees and Stay180 Pro
The calculator is available without payment. Stay180 Pro is sold on the Pricing page (currently US$4 per month, US$36 per year, or US$49 as a lifetime licence). Features included with Pro are described on that page and may change.
Paid subscriptions renew until cancelled, except a lifetime licence, which does not renew. Taxes may apply. Fees are generally non-refundable except where required by law or where we state otherwise at checkout.
Checkout is handled by Stripe. By completing a purchase you also agree to Stripe’s terms for that payment.
We may suspend or limit paid features for non-payment, abuse, or risk to the Service.
Intellectual property
We and our licensors own the Service, including software, branding, and documentation. These Terms do not transfer that ownership.
Feedback you provide may be used to improve the Service without obligation to you.
Disclaimer
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT UNINTERRUPTED OR ERROR-FREE OPERATION, THAT CALCULATOR RESULTS WILL MATCH ANY AUTHORITY’S DETERMINATION, OR THAT RESULTS ARE SUITABLE FOR TRAVEL, VISA, OR BORDER DECISIONS.
Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE FEES YOU PAID US FOR THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY (OR, IF YOU PAID NO FEES, FIFTY US DOLLARS).
WE WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, TRAVEL, OR GOODWILL, EVEN IF ADVISED OF THE POSSIBILITY — INCLUDING REFUSED ENTRY, FINES, OR DISRUPTED TRAVEL.
Nothing in these Terms excludes liability that cannot be excluded under England and Wales law (including for death or personal injury caused by negligence, or fraud).
Indemnity
You will defend and indemnify us against third-party claims arising from stays or calendar data you handle in the Service, your use of Google or other third-party services, your breach of these Terms, or your violation of law, except to the extent caused by our willful misconduct.
Term and termination
You may stop using the Service at any time. You may cancel a recurring Stay180 Pro subscription through Stripe’s billing flow or by contacting support@stay180.app. A lifetime licence does not renew; we may still stop providing the Service.
We may terminate or suspend access for material breach, unlawful use, or risk to the platform.
Because confirmed stays live on your device, stopping use or clearing the site does not require us to delete a server copy of those stays — we do not hold one. You can delete stays in the product or by clearing this site’s data in your browser.
Governing law
These Terms are governed by the laws of England and Wales, without regard to conflict-of-law rules. Courts of England and Wales have exclusive jurisdiction, except that either party may seek injunctive relief in any competent court.
Changes
We may update these Terms by posting a revised version and updating the “Last updated” date. Material changes will be highlighted where practicable. Continued use after the effective date constitutes acceptance, except where applicable law requires a different process.
