Privacy
Policy.

Scope and who we are

This Privacy Policy applies to the Tacklo and Решала mobile applications (together, the “App”) and related services operated by the App's developer (“we”, “us”, or “our”). The App provides study tools, AI-assisted explanations, textbook answers, notes, reminders, chat, feedback, and notifications.

By using the App, you acknowledge the practices described here. Some features may ask for separate permission or consent before they process particular information.

Information we collect

Information you provide

• Questions, chat messages, and other content you submit to receive study help.
• Notes, reminders, selected textbooks, grades, subjects, and tasks.
• Feedback, an optional contact email, and photos or files you choose to attach.

App, device, and network information

• App version and build, device model, operating system, language, and store or distribution channel.
• An app or device instance identifier used to operate the service and keep it secure.
• IP address, network information, and general region inferred from an IP address.

Usage, diagnostics, and notifications

• Feature interactions, screens viewed, textbook and task activity, ad events, and notification interactions.
• Error, performance, and diagnostic information.
• Push-notification tokens and provider information, such as FCM, APNs, HMS, or RuStore.

Advertising information

Advertising partners may process an advertising identifier (such as IDFA or Android Advertising ID) when permitted, IP address, device information, ad impressions and interactions, and information used for ad delivery, measurement, fraud prevention, and frequency control. The App does not request precise GPS location for advertising.

How we use information

We use information to:

• Provide answers, explanations, chat, notes, reminders, and other requested features.
• Process submitted content through our servers and AI service providers.
• Remember preferences, synchronize content, and deliver push notifications.
• Respond to feedback and troubleshoot technical issues.
• Understand App usage and improve functionality, quality, and safety.
• Deliver and measure ads, subject to consent and age-related restrictions.
• Detect abuse, prevent fraud, protect users, and comply with law.

Where applicable, our legal bases include performing our agreement with you, your consent, our legitimate interests in operating and improving the App, and compliance with legal obligations. Please avoid entering sensitive personal information into AI chat or feedback unless it is necessary for your request.

How we share information

We may share relevant information with:

• Cloud, hosting, and AI providers that process requests and operate the App on our behalf.
• Google AdMob and its demand partners and Yandex Mobile Ads for advertising, measurement, security, and fraud prevention.
• Google Firebase Cloud Messaging and platform push services to deliver notifications.
• Yandex AppMetrica for analytics, diagnostics, and product improvement.
• Apple, Google, Huawei, and RuStore when their app stores or platform services independently process information.
• Authorities or other parties when required by law, necessary to protect rights and safety, or involved in a business reorganization.

We do not sell personal information for money. Depending on local law, disclosure of an advertising identifier or device activity for personalized advertising may be considered “sharing” or “targeted advertising”; the controls below let you limit it.

Advertising and consent

The App may display ads from Google AdMob or Yandex Mobile Ads. Where required, we ask for consent before requesting personalized ads. On iOS, the system may also ask whether you allow tracking across other companies' apps and websites. If you decline, the App may still show contextual, non-personalized, or limited ads. Those ads may still use information such as IP address and basic device data for delivery, reporting, security, and fraud prevention.

We do not knowingly use personal information of a user known to be below the minimum age required by applicable law for interest-based advertising. You can change ad consent in the App where that control is available, change tracking permissions in device settings, or reset/delete your device's advertising identifier.

Retention, transfers, and security

We keep information only as long as reasonably necessary for the purposes described in this Policy. Chats, notes, and reminders may remain until you delete them or request deletion. Support records may be retained while needed to resolve a request and meet legal obligations. Push tokens are retained until they expire, become invalid, or you unsubscribe. Security, diagnostic, and analytics records are retained according to operational needs and the applicable provider's retention settings. Backups may persist for a limited period before being overwritten.

Service providers may process information in countries other than yours. Where required, we use appropriate safeguards for international transfers. We use technical and organizational safeguards, including encrypted network transmission and access controls, but no online service can guarantee absolute security.

Your choices and rights

Depending on where you live, you may have the right to:

• Request access to, correction of, deletion of, or a copy of your personal information.
• Object to or restrict certain processing and withdraw consent at any time.
• Opt out of targeted advertising or the sharing of information for that purpose.
• Complain to your local data-protection authority.

You can delete individual chats, notes, and reminders inside the App; disable notifications or tracking in device settings; and use the App's consent controls where available. For a broader access or deletion request, contact us below. We may need to verify the request and retain limited information where the law permits or requires it.

Children's privacy

The App is a study tool and may be used by children. A parent or guardian should review this Policy and supervise a child's use where required by law. Children should not enter their full name, address, phone number, school, precise location, or other unnecessary personal details into chat, feedback, or notes.

We do not knowingly collect more personal information from a child than is needed to provide the requested service. If you are a parent or guardian and believe a child has provided personal information improperly, contact us so we can review and delete it as appropriate.

Changes to this Policy

We may update this Policy when the App, our providers, or legal requirements change. We will post the revised version here and update the date at the top. If a change materially affects your rights, we will provide additional notice where required.
