This license shall automatically terminate if you violate any of these restrictions and may be terminated by sentient being software at any time. Upon terminating your viewing of these materials or upon the termination of this license, you must destroy any downloaded materials in your possession whether in electronic or printed format.
Open-source software. Software that we publish under an open-source license, such as GridMind (Apache License 2.0, available at https://github.com/sentientbeingsoftware/gridmind), is governed by that license. Nothing in this section limits the rights that license gives you.

Further, sentient being software does not warrant or make any representations concerning the accuracy, likely results, or reliability of the use of the materials on its website or otherwise relating to such materials or on any sites linked to this site.
In no event shall sentient being software or its suppliers be liable for any damages (including, without limitation, damages for loss of data or profit, or due to business interruption) arising out of the use or inability to use the materials on sentient being software's website or applications provided by sentient being software, even if sentient being software or a sentient being software authorized representative has been notified orally or in writing of the possibility of such damage. Because some jurisdictions do not allow limitations on implied warranties, or limitations of liability for consequential or incidental damages, these limitations may not apply to you.
The materials appearing on sentient being software's website could include technical, typographical, or photographic errors. sentient being software does not warrant that any of the materials on its website are accurate, complete or current. sentient being software may make changes to the materials contained on its website at any time without notice. However sentient being software does not make any commitment to update the materials.
sentient being software has not reviewed all of the sites linked to its website and is not responsible for the contents of any such linked site. The inclusion of any link does not imply endorsement by sentient being software of the site. Use of any such linked website is at the user's own risk.
sentient being software may revise these terms of service for its website and applications at any time without notice. By using this website and the applications provided by sentient being software you are agreeing to be bound by the then current version of these terms of service.
These terms and conditions are governed by and construed in accordance with the laws of US and you irrevocably submit to the exclusive jurisdiction of the courts in that State or location.
Your privacy is important to us.
It is sentient being software's policy to respect your privacy regarding any information we may collect while operating our website. Accordingly, we have developed this privacy policy in order for you to understand how we collect, use, communicate, disclose and otherwise make use of personal information. We have outlined our privacy policy below.
We will collect personal information by lawful and fair means and, where appropriate, with the knowledge or consent of the individual concerned.
Before or at the time of collecting personal information, we will identify the purposes for which information is being collected.
We will collect and use personal information solely for fulfilling those purposes specified by us and for other ancillary purposes, unless we obtain the consent of the individual concerned or as required by law.
Personal data should be relevant to the purposes for which it is to be used, and, to the extent necessary for those purposes, should be accurate, complete, and up-to-date.
We will protect personal information by using reasonable security safeguards against loss or theft, as well as unauthorized access, disclosure, copying, use or modification.
We will make readily available to customers information about our policies and practices relating to the management of personal information.
We will only retain personal information for as long as necessary for the fulfilment of those purposes.
We are committed to conducting our business in accordance with these principles in order to ensure that the confidentiality of personal information is protected and maintained. sentient being software may change this privacy policy from time to time at sentient being software's sole discretion.
GridMind is a collection of grid-based puzzle, memory and arcade mini-games published by Sentient Being Software LLC ("we", "us"). This section describes what the GridMind app does with information. It applies to GridMind on every platform where we publish it.
The short version
There are no accounts, no ads, and no third-party analytics or crash-reporting tools.
Your scores, settings and favorites stay on your device.
Anonymous usage diagnostics are off unless you say yes, and you can turn them off at any time.
Feedback you submit from the app becomes a public GitHub issue. Do not put personal information in it.
1. What stays on your device
GridMind saves these on your device: your theme and color palette (including custom colors), favorite games, the options you last used for each game, high scores, background music choice, which game walkthroughs you have seen, and your choice about usage diagnostics. We do not receive this information, except for the items you may attach to feedback (see section 3). It is removed when you uninstall the app or clear its storage. On Android, Google may also back these settings and scores up to your own Google account and restore them if you reinstall the app or move to a new phone. That backup is handled by Android and your Google account; we do not receive it.
2. Anonymous usage diagnostics (optional, off by default)
The first time you open the app, it asks whether you want to share anonymous usage statistics. Nothing is collected unless you choose Allow.
If you allow it, after each game session (whether you won, lost or quit) the app records: which game, when the session started, how long it lasted, the outcome (victory, game over or quit), the game options selected for that session, and a timestamp. These are sent over HTTPS to a server we operate, together with the app name and app version. They are sent in batches of five events, when the app starts, and when the app moves to the background.
This data contains no name, email address, account, advertising ID, device ID or location, and it is not linked to any feedback you send.
You can change your choice at any time in Settings > Privacy > Anonymous Diagnostics. Turning it off stops collection and deletes any events that have not been sent yet. Because diagnostics that were already sent carry no identifier, we cannot tell which ones came from your device, so we cannot delete them individually.
3. Feedback you choose to send
Feedback is sent only when you press Submit Feedback (Settings > Submit Feedback / Report Issue).
Public. Your feedback is posted as a public issue at https://github.com/sentientbeingsoftware/gridmind. Anyone can read and copy it. The public issue contains:
the title and description you write, and the feedback type you choose;
the app version, your operating system name and version, and a generic device label;
the connection type (native app or browser);
a random session ID. It is created each time the app starts, is not stored on your device, and is not linked to you;
if "Attach diagnostic metadata" is on (it is on by default, and you can switch it off before sending): your high scores, color palette type and theme mode.
Please do not put names, email addresses, passwords or other personal information in the title or description. If you do by mistake, contact us (see "Contact" below) and we will delete the issue. We cannot recall copies that other people have already made.
Private. If you enter an email address, it is not posted to the public issue. It is stored privately and used only to reply to you about your feedback.
4. What the app does not do
GridMind has no accounts or sign-in, shows no ads, and includes no third-party analytics, advertising or crash-reporting software. It does not ask for access to your location, contacts, camera, microphone, photos or files. Its only permission is internet access, which it uses to send diagnostics and feedback if you choose to. We do not sell your data.
5. Servers and other companies
The server we operate receives diagnostics and feedback. As with any internet connection, it receives your device's IP address and standard connection information.
GitHub hosts the public feedback issues. GitHub's own privacy statement applies to how GitHub handles that content.
Google Play distributes the app. Google's terms and privacy policy apply to your use of Google Play.
The Settings screen has support links (Buy Me a Coffee and Ko-fi) and a link to this page. They open in your browser, and the other site's policies apply once you leave GridMind.
6. How long we keep information
On your device: until you uninstall the app or clear its storage. If Android backup is on, a copy stays in your Google account until you delete it there or turn backup off.
Diagnostics: only as long as they are useful for improving the game.
Feedback issues: they stay public until we delete them.
Feedback email addresses: only as long as needed to respond to you.
7. Security
Diagnostics and feedback are sent over HTTPS. We use reasonable safeguards, but no method of storage or transmission is completely secure.
8. Children
GridMind is a general-audience puzzle game. We do not knowingly collect personal information from children under 13. Diagnostics are anonymous and off by default, and feedback is optional. If you believe a child has submitted personal information, contact us and we will remove it.
9. Your choices and rights
You can turn diagnostics off, choose not to send feedback, or uninstall the app at any time. You can also ask us to delete a feedback issue or an email address you gave us. Depending on where you live (for example the European Economic Area, the United Kingdom or California), you may have additional rights to access, correct or delete personal information we hold. Because we do not keep accounts, we may need the link to your issue or the email address you used in order to find your information.
10. Changes
We will post changes to this policy on this page and update the "Last updated" date above.
