Privacy Policy

Recursive Ink, the developer of Sundown¹, has a deep-rooted respect for personal privacy. We are not in the business of collecting, sharing, or selling information about our users. This policy describes what data we collect, how we use it, and what rights you may have under applicable privacy laws, such as the General Data Protection Regulation (GDPR) or the California Online Privacy Protection Act (CalOPPA).

The current version of this privacy policy is effective as of 2026-05-16. We may update this policy from time to time. You can review the current version of the policy at sundown.recursive.ink/privacy where a summary of changes is also maintained. It is your responsibility to review this policy periodically. If we make significant changes, you will be notified within the app.

What Data We Collect

The Sundown app is designed to respect your privacy by default.

• We do not collect any personal information through the Sundown app.
• We do not track how you use the app.
• We do not use cookies, analytics, or advertising trackers on our website or in the app.

We do log some technical data when you visit our website. This data may include your IP address, timestamps, and other request metadata. We use this data only for service provision, abuse prevention, diagnostics, and security. It is not linked to your identity and is retained temporarily or as required for service provision.

Additionally, the Apple App Store provides us with aggregated and anonymous statistics about downloads, in-app purchases, and general app performance; but, again, such statistics are not linked to you personally.

If you choose to contact us (by email, through our contact form, or within the app), we will retain your message, including any personal data you provide (such as your name and email address), for the purpose of responding to you and maintaining a record of the conversation. Such communications may be stored for as long as necessary to respond to your inquiry and for record-keeping purposes, unless you request deletion.

For any personal data you voluntarily provide to us (e.g., via email), we rely on your explicit consent as the lawful basis for processing. For technical or security-related data (e.g., IP address logs), we rely on our legitimate interests in maintaining and protecting the Sundown service.

How We Protect Your Data

Although we currently collect minimal personal data, we take confidentiality and data security seriously. Any personal data you share with us (such as through email communications) is stored under strict security precautions. Should we collect additional data in the future, we will ensure all processing remains in line with any applicable privacy laws.

Any personal data we hold may be processed or stored in jurisdictions other than your own. At present, we use servers physically located in the United Kingdom and the European Union. Where personal data is transferred outside of the UK or EU, we ensure appropriate safeguards are in place, such as relying on adequacy decisions or standard contractual clauses approved by the European Commission or UK authorities.

Access to any personal data is restricted to authorized personnel who require it in order to provide support or maintain our services.

Your Rights

Under privacy laws, such as the GDPR and the CalOPPA, you may have the right to:

• Access the personal data we hold about you,
• Correct inaccurate or incomplete information,
• Request deletion of your personal data,
• Object to or restrict certain processing,
• Withdraw your consent at any time,
• Lodge a complaint with your data protection authority.

You can exercise these rights by emailing us at privacy@recursive.ink. We will respond within 28 days.

Please note: These rights apply only to the extremely limited personal data that we might hold about you (e.g., from correspondence). We do not collect or hold any personal information based on ordinary use of the Sundown app or website.

Children’s Privacy

Sundown is not explicitly marketed toward children and we do not knowingly collect personal data from children. If you are a parent or guardian and believe that your child under 13 (or the applicable age threshold in your jurisdiction) has provided us with personal information, please contact us at privacy@recursive.ink. We will take steps to delete such information promptly.

Data Controller

Recursive Ink Ltd is the data controller responsible for your personal data under this policy. Our registered address is: 50C Rodney Street, Liverpool, L1 9AA, United Kingdom. You can contact us regarding privacy matters at: privacy@recursive.ink

¹ Sundown is also marketed as مزولة, 夕阳下, and 夕陽下 in other regions.
