Terms of Use
Last updated: 10 November 2026
1. Who we are
These terms govern your use of tessalun.com and the Lantern website scanner at scan.tessalun.com (together, "the service"), operated by TessaLun obrt, OIB 43045606650, Wickerhauserova ul. 12, 10000 Zagreb, Croatia. By using the service or creating an account, you accept these terms.
2. Account
You need an account to see scan results. Provide a real email address, keep access to it secure and do not share your account. One person or company — one account. We may suspend accounts that break these terms.
3. Acceptable use
Only scan websites that you own or are authorised to analyse, or publicly available websites in a normal, non-disruptive way. Do not try to bypass limits, overload third-party websites, scrape the service, test its security without permission or use it for anything unlawful. We apply daily and monthly scan limits and may change them.
4. Scan results and reports
Results are generated automatically from public data, third-party tools (such as Google PageSpeed Insights) and AI models. They are estimates and recommendations, not guarantees. AI visibility results can differ between runs and over time. We do not guarantee any ranking, traffic, sales or other outcome from following the recommendations. You decide what to change on your website and are responsible for it.
5. Paid reports
Paid reports are one-time digital purchases processed by Stripe, which may show its own terms at checkout. Prices are shown before payment. A paid report may include a credit towards a TessaLun project under the conditions stated at purchase. Refunds follow our Refund Policy.
6. Intellectual property
The service, its design and texts belong to TessaLun. Your reports are for your own use and for sharing within your business. Website content that you scan remains the property of its owners.
7. Availability and changes
We work to keep the service available but do not promise it will be uninterrupted or error-free. We may change, limit or stop features of the free scanner at any time.
8. Liability
The service is provided "as is". To the extent permitted by law, we are not liable for indirect losses, lost profits or data, or for decisions you make based on the results. Our total liability related to a paid report is limited to the amount you paid for it. Nothing in these terms limits liability that cannot be limited by law or your mandatory consumer rights.
9. Privacy
How we handle personal data is described in our Privacy Policy.
10. Law and contact
These terms are governed by the law of the Republic of Croatia, without prejudice to mandatory consumer protection rules of your country of residence. Disputes are handled by the competent courts in Zagreb, unless mandatory rules allow you to go to court where you live. Questions: hello@tessalun.com.
