Checkmate: Smart Checklists (“Checkmate”, “the App”, “we”, “us”, or “our”) is developed and operated by Youtility LTD.
Your privacy is important to us. This Privacy Policy explains what information we collect, why we collect it, how it is stored and used, when it may be shared, and the choices and rights available to you when using Checkmate.
Checkmate combines local device storage with cloud-based features. Some information may remain solely on your device, while information required for accounts, social features, sharing, messaging, synchronisation, moderation, and other online functionality may be stored and processed using cloud services.
By using Checkmate, you acknowledge the data practices described in this Privacy Policy.
The information we collect depends on which Checkmate features you use.
When you create or use a Checkmate account, we may collect information including:
We use this information to create and maintain your account, authenticate you, provide account features, communicate with you, prevent misuse, and operate the service.
We do not directly store your password in readable form.
Checkmate may process information you create within the App, including:
Some checklist information may be stored locally on your device. Content that you choose to synchronise, publish, share, or use with online features may be stored using our cloud infrastructure.
When using Checkmate’s social or community features, we may collect and store information such as:
Content you intentionally publish publicly or share with other users may be visible to those users or to the wider Checkmate community depending on the feature and your selected settings.
You should avoid posting personal, confidential, or sensitive information publicly.
If you use messaging or communication features within Checkmate, we may process and store information necessary to provide those features, including:
Messages should not be considered end-to-end encrypted unless the App explicitly states otherwise.
Authorised Youtility LTD administrators may have technical access to certain stored information where reasonably necessary to operate the service, provide support, investigate reports, enforce our rules, prevent abuse or fraud, maintain security, or comply with legal obligations.
We do not routinely access private user content without a legitimate operational, safety, security, support, moderation, or legal reason.
We may collect information about how Checkmate is used, including:
We use this information to understand how Checkmate is used, improve features, identify problems, and improve the user experience.

Other information required for online functionality may be stored remotely. This can include account information, social content, shared content, messages, interactions, and other information necessary to provide cloud-based features.
We currently use Supabase as part of our cloud infrastructure and backend services.

We may also disclose information where reasonably necessary to:
Some of our service providers may process information outside the United Kingdom or the country in which you live.
Where required by applicable data protection law, we take appropriate steps to ensure that international transfers of personal information are subject to suitable safeguards.
Third-party providers may also maintain their own mechanisms for lawful international data transfers.
We retain personal information only for as long as reasonably necessary for the purposes for which it was collected, including providing Checkmate, maintaining security, resolving disputes, complying with legal obligations, and enforcing our agreements.
Retention periods may vary depending on the type of information and why it is processed.
When an account is deleted, associated personal information will be deleted, anonymised, or otherwise handled in accordance with applicable law and our technical and legal requirements.
Some information may need to be retained for a limited period after deletion where necessary for:
Public content or information shared with other users may not always be immediately removable from copies already received or created by other users.

Deleting the App from your device does not necessarily delete your Checkmate account or cloud-stored information.

Under UK data protection law, these may include the right to:

Checkmate is not intended for children under the minimum age permitted to use the service in their jurisdiction.
We do not knowingly seek to collect personal information from children who are not legally permitted to use the service without any consent or authorisation required by applicable law.
If we become aware that personal information has been collected from a child in circumstances where it should not have been collected, we may take steps to delete the information and/or restrict the associated account.
Parents or guardians who believe a child has provided personal information contrary to these requirements should contact us.
We take reasonable technical and organisational measures designed to protect information processed through Checkmate.
These may include access controls, authentication mechanisms, secure cloud infrastructure, and restrictions on administrative access.
However, no internet-connected service, database, or storage system can guarantee absolute security.
You are responsible for keeping your account credentials secure and should not share authentication information with other people.
If you believe your Checkmate account has been compromised, contact us as soon as possible.
Checkmate may contain links to external websites, services, or content operated by third parties.
We are not responsible for the privacy practices, security, or content of third-party services.
We recommend reviewing the privacy policies of third-party services before providing personal information to them.
We may update this Privacy Policy as Checkmate develops, our data practices change, or legal requirements change.
When we make changes, we will update the “Last updated” date at the top of this Privacy Policy.
Where required, we may provide additional notice within the App or through other appropriate means when significant changes are made.
