Terms of Service

Last updated: 11 November 2025

These Terms and Conditions (“Terms”) govern your use of Poterna, a privacy-first web analytics service provided by Poterna Ltd (a company registered in the UK). When we say “service” in this document, we are referring to Poterna Ltd. By using the Service, you agree to comply with these Terms. If you do not agree, do not use the Service.

Service Description and Scope

  • The Service provides website analytics by collecting only anonymized metrics (e.g. page views, basic clicks). We do not store IP addresses or other personal identifiers. Data is hashed (IP+User-Agent with daily salt) so that individual users cannot be identified.

  • You install our lightweight analytics script in the <head> of your web pages. We supply the script and instructions; you are responsible for embedding it correctly.

  • The Service itself does not include built-in dashboards or charts. Instead, analytics data is displayed via external visualization tools. (Any charts or reports must be requested from our team.)

  • While we aim to provide a useful service, it is offered “as-is” and without guarantees that it will meet all individual requirements or expectations.

User Accounts and Responsibilities

To use the Service, you must create an account. You agree that:

  • You will provide complete and accurate information when registering (such as valid email). You are responsible for keeping your account details up to date. Failing to do so is a breach of these Terms.

  • You are solely responsible for maintaining the security of your account credentials (username, password, etc.). You must notify us immediately of any unauthorized use or breach. You are responsible for all activities that occur under your account, even if done by others using your credentials.

  • You will use the Service only for lawful purposes. You may not use the Service to engage in illegal activities or violate any laws or regulations. For example, do not use the analytics data in a way that infringes on anyone’s privacy or intellectual property rights.

  • You agree to implement the provided tracking script only on websites you own or have permission to modify. You may not attempt to interfere with or reverse-engineer the script or the Service. (As a privacy-focused analytics provider, we monitor compliance with our rules and may suspend accounts that misuse the Service.)

Plans & Billing

  • We offer a free plan (at no cost) with limited features and usage. The free plan grants you a certain amount of monthly page views and basic analytics functionality. We may limit or suspend free accounts that violate the usage policies or exceed free-plan limits.

  • If you exceed free-plan limits or choose a paid tier, you must upgrade to a paid subscription. Paid subscriptions are billed in advance on a recurring basis (monthly or annual, as selected). When you sign up for a paid plan, you will provide valid payment information (e.g. credit card). You authorize us to charge your payment method for the subscription fees and any applicable taxes.

  • Paid subscriptions automatically renew at the end of each billing cycle. You may cancel the auto-renewal at any time through your account settings; cancellation will take effect immediately (no further charges will occur). If you do not cancel, the subscription will renew under the same terms.

  • You agree to keep your billing information up to date and to notify us promptly if your payment method changes or expires. If we are unable to process your payment on time, we may limit access to services for your account and downgrade account to the free plan.

  • All fees for paid subscriptions are non-refundable, except where required by applicable law. Once you pay for a period (month or year), that fee is earned and will not be returned if you cancel or do not use the Service.

Cancellation and Termination

  • You may cancel or downgrade your paid plan at any time from your account dashboard. Cancellation takes effect at the end of your current billing period. No refunds will be issued for partial periods.

  • You are solely responsible for cancelling auto-renewal when you wish to stop the Service. Contacting us by email alone does not count as cancellation.

  • We may suspend or terminate your account (free or paid) if you breach these Terms.

Disclaimer and Limitation of Liability

We do our best to offer a reliable and privacy-friendly analytics service, but like any software, things may not always work perfectly.

  • The Service is provided “as is” — without warranties of any kind. We can’t guarantee that it will be uninterrupted, error-free, or completely secure. There may occasionally be bugs or downtime, though we always aim to minimize disruptions.

  • You’re responsible for how you interpret and use the analytics data. We don’t promise specific outcomes or improvements. Please make sure the Service fits your needs before relying on it.

  • To the extent permitted by law, Poterna Ltd and its team won’t be liable for any indirect or unexpected losses — like lost profits, business interruption, or data issues — even if we were warned it might happen. If something does go wrong, our total liability is capped at the amount you paid us in the past 12 months (or £100, whichever is greater).

  • Some parts of the experience (like data visualizations) rely on third-party services we integrate with. While we do our best to keep everything running smoothly, we can’t take responsibility for those external tools or how they behave. If you export your data elsewhere, that’s entirely up to you.

Service Availability and Uptime

  • We strive to provide a reliable service, but we do not offer a formal Service Level Agreement or guaranteed uptime. The Service is offered on a best-effort basis. We will use commercially reasonable efforts to maintain operation and address outages, but we do not guarantee any specific percentage of uptime.

  • We provide support via email and on-site chat only. While our team aims to respond promptly, support is offered on a best-effort basis and we do not guarantee any specific response time.

Changes to Terms

We may update these Terms from time to time — for example, when we improve the service, add features, or adjust to new legal requirements. When we do, we’ll post the new version on our website, and it will take effect immediately.

We encourage you to check back occasionally to stay up to date. By continuing to use the Service after changes are posted, you agree to the updated Terms. We’ll do our best to keep updates clear and reasonable.

Governing Law and Jurisdiction

These Terms are governed by the laws of England and Wales. Any dispute arising out of or relating to these Terms or the Service shall be subject to the exclusive jurisdiction of the courts of England and Wales.
