Privacy Policy

Last updated: May 7, 2026

This Privacy Policy explains how Knotwise Games ("Knotwise", "we", "us", "our") collects, uses, shares and protects information about you when you use our website and the games and services available through it (collectively, the "Services").

We're a small team and we try to take a small-team approach to data: collect what we genuinely need, keep it for as long as we genuinely need it, and be honest about what we do with it. If anything below is unclear, please email us at hello@knotwise.games.

1. Data Controller

Knotwise Games is the data controller responsible for personal data we collect about you in connection with the Services. You can reach us at hello@knotwise.games.

2. Children

The Services are not directed to children under the age of 13 (or the equivalent minimum age in your country). We don't knowingly collect personal data from children under that age. If you believe a child has provided us with personal data, please contact us and we will delete it.

3. Personal Data We Collect

Depending on how you use the Services, we may collect the following categories of personal data:

• Account information. When you create an account we collect your email address and a hashed password (or, for sign-in via a third-party provider, the identifier and email address that provider shares with us).
• Subscription and billing information. If you purchase a subscription, our payment processor (Stripe) collects payment-card details on our behalf. We never see or store your full card number; we receive a token, the last four digits, expiry date, and country.
• Usage information. We collect information about how you use the Services, such as which puzzles you play, when, and from what kind of device. This includes IP address, browser type, device identifiers, pages visited, and timestamps.
• Communications. When you email us or fill in a contact form, we keep your message and our reply so we can pick up the conversation if it continues.
• Cookies and similar technologies. We use cookies and similar technologies as described in our Cookies page.

4. Our Legal Bases For Processing Your Information

Where applicable law (such as the UK GDPR or EU GDPR) requires us to identify a legal basis for processing your personal data, we rely on:

• Contractual necessity — to provide the Services you've asked for, including running your account and processing payments;
• Legitimate interests — to keep the Services secure, debug problems, understand how the Services are used, and prevent abuse;
• Consent — for non-essential cookies and certain marketing communications, where consent is required; you can withdraw consent at any time;
• Legal obligation — to comply with our legal and regulatory obligations.

5. How We Use Personal Data

We use personal data to:

• create and manage your account and provide the Services;
• process subscriptions, taxes, refunds and other payments;
• save your puzzle progress and personalise your experience;
• communicate with you about your account, security, or important changes to the Services;
• send you newsletters or product updates if you've signed up to receive them (you can unsubscribe at any time);
• monitor and analyse usage of the Services so we can improve them;
• detect, investigate and prevent fraud, abuse, or violations of our Terms; and
• comply with our legal obligations.

6. Sharing and Disclosure of Personal Data

We don't sell your personal data. We share it only with:

• Service providers that help us run the Services, such as our hosting provider, payment processor, email delivery provider and analytics tools. These providers act as our processors and are bound by contracts to protect your data.
• Authorities where we're legally required to disclose information, or to protect our rights, our users, or the public.
• Successors in the event of a merger, acquisition, financing or sale of business assets, in which case personal data may be transferred to the relevant party.

7. Where, How and How Long We Store Your Information

Your personal data is stored on servers operated by our hosting and infrastructure providers, which may be located outside the country in which you live. Where personal data is transferred internationally we rely on appropriate safeguards, such as standard contractual clauses, where required by law.

We keep personal data for only as long as we need it for the purposes described in this Policy or as required by law. When we no longer need it, we delete it or anonymise it.

8. Data Security

We use reasonable technical and organisational measures to protect personal data from loss, misuse, unauthorised access, disclosure, alteration and destruction. No method of transmission over the internet is 100% secure, and we can't guarantee absolute security — but we work hard to keep your data safe and to respond promptly if something goes wrong.

9. Your Rights and Choices

Depending on where you live, you may have rights to:

• access the personal data we hold about you;
• correct inaccurate or incomplete data;
• delete your data, subject to certain exceptions;
• object to or restrict certain processing;
• request a portable copy of your data;
• withdraw consent where we rely on consent; and
• lodge a complaint with your local data protection authority.

To exercise any of these rights, email us at hello@knotwise.games. We may need to verify your identity before responding.

You can also:

• Unsubscribe from marketing emails by clicking the unsubscribe link in any email we send.
• Manage cookie preferences via the controls described on our Cookies page.
• Close your account at any time from your account settings.

10. Changes to the Privacy Policy

We may update this Privacy Policy from time to time. When we do we'll change the "Last updated" date at the top of this page and, if the changes are material, we'll let you know through the Services or by email. We encourage you to review this Policy periodically.
