Privacy Policy

Last updated: October 28, 2026

This policy covers Syberchess, its support service, and this website. Leonardo Bohac is responsible for the personal information handled through our support service. For questions or requests, contact [email protected].

Playing the game

The app works offline and requires no account. It does not send gameplay, preferences, or personal information to the developer. It contains no advertising, tracking, or analytics SDKs, and does not sell personal information or use it for targeted advertising.

Local settings and backups

The app saves settings such as training options, colors, and piece design on your device. We cannot access or remotely delete these local settings. Deleting the app, rather than offloading it, removes its local data from the device. Copies may remain in device or iCloud backups, depending on your settings, and may return when you restore a backup. Manage those copies through your device or backup service. See Apple's information about iCloud backups.

Support messages

If you email us, we receive your email address, any sender name, the message, and any attachments or diagnostic details you choose to send. We use that information to respond, investigate reported issues, maintain the app, and handle privacy or legal requests. Please send only what is needed to describe the issue. You can play without contacting us, although we may need relevant details to help with a particular support request.

Support email is received through Amazon Web Services (AWS) and forwarded to our private Gmail inbox. Originals are stored in a private, encrypted AWS bucket with automatic expiration after 30 days. The forwarding service sends a plain-text preview, without attachments or embedded content. Messages that cannot be safely previewed remain in private storage for manual inspection. Technical logs contain delivery references and status, not message bodies, and expire after 14 days. See the AWS Privacy Notice and Google Privacy Policy. We do not use support messages for advertising or mailing lists. Where a legal basis is required, we rely on applicable grounds for responding to your request, our legitimate interests in providing support and fixing problems, or compliance with legal obligations, subject to your rights under applicable law.

This website

This static site is hosted by Cloudflare Pages. It has no analytics scripts, advertising trackers, contact forms, or cookies added by us. Cloudflare processes technical information, such as IP addresses and request data, to deliver and secure the website. This is separate from playing the offline game. See the Cloudflare Privacy Policy.

Apple services and other providers

Apple handles App Store distribution and its own platform services. We may receive aggregate App Store statistics or diagnostic reports that Apple makes available according to its services and your sharing settings. These are not collected by an analytics SDK in Syberchess. See Apple's privacy information and your device's Analytics & Improvements settings.

Email, hosting, and platform providers may process information in countries other than your own under their applicable terms and privacy policies. We use support information only for the purposes above and disclose it only as needed to provide support, comply with applicable law, or establish, exercise, or defend legal rights. Following an external link is subject to that provider's privacy practices.

Retention and your choices

Support correspondence is retained only while needed to answer your request, investigate related issues, or meet applicable legal obligations and resolve disputes. Information no longer needed for those purposes is deleted or de-identified. The 30-day expiration above applies to original messages in AWS, not to correspondence retained in our support inbox. Providers control their own security logs and backup retention under their policies.

You can contact us to request access, correction, or deletion of information we hold about you. Depending on applicable law, you may also have rights to object to or restrict processing, obtain a copy of your information, withdraw consent where processing relies on it, or complain to a relevant privacy authority. We may need limited information to verify a request and will explain any lawful reason we cannot fully comply. There is no game account to delete.

Children and policy updates

Playing the game does not require children to submit personal information. A parent or guardian can contact us about information included in a child's support message or request its removal, subject to applicable law.

Changes to this policy will be posted here with an updated date. Any changes to how personal information is handled remain subject to applicable notice and consent requirements.
