Privacy Policy

PRAVIEL is operated by Anton Soloviev, doing business as PRAVIEL, from the United States ("PRAVIEL," "we," or "us"). This policy applies to the PRAVIEL apps for iOS, Android, and the web, to praviel.com and our other websites, and to related services and communications (together, the "Service").

Third-party platforms you reach through PRAVIEL, such as app stores, Discord, and payment or donation platforms, handle your information under their own policies.

What we collect depends on how you use the Service. It falls into these categories:

• Provide, maintain, and sync the Service, including lessons, the Coach, the Reader, review, and your progress.
• Personalize your experience, including with optional information you choose to share.
• Understand how the Service is used and develop, test, and improve features and content.
• Detect, investigate, and fix errors, crashes, and performance problems.
• Protect the Service and the people who use it, including preventing fraud, spam, and abuse, and enforcing our Terms.
• Communicate with you about your account, your requests, and changes to the Service.
• Process purchases and handle refunds, chargebacks, and disputes.
• Comply with the law, respond to lawful requests, and establish, exercise, or defend legal claims.

On our websites, analytics stay off until you opt in through the privacy controls. When you opt in, we use a privacy-focused analytics service, route events through our own servers, and set no advertising cookies.

In the apps, we measure usage with our own first-party analytics rather than an advertising or analytics network.

We use error-monitoring tools, including Sentry, to find and fix crashes and errors. Error reports are limited to technical details, and they are sent whether or not you enable optional analytics, because we need them to keep the Service working.

We use cookies and similar storage, such as browser local storage and on-device storage in the apps, to keep you signed in, remember your settings, record your privacy choices, and keep the Service secure.

We do not use third-party advertising cookies or cross-site tracking pixels. Because we do not track you across other websites, our practices are the same whether or not your browser sends a Do Not Track signal.

You can clear or block cookies in your browser settings. Some features may not work without them, and you may need to set your preferences again.

Some features, such as the Coach, Reader help, and pronunciation feedback, send the content they need to third-party AI providers for processing. That content can include your messages and questions, voice recordings, the text you are studying, recent conversation context, and personalization details you have turned on.

We currently use AI services from OpenAI, Anthropic, and Google. Providers, models, and features may change. We do not intentionally include your name, email address, or account credentials in AI requests, and we do not intentionally keep pronunciation audio after it is processed.

Lessons are prepared in advance, so ordinary lessons do not send your information to AI providers.

Do not submit sensitive personal information in free-text fields or recordings. AI output can be wrong, so check anything important.

We share information only as described here:

• Service providers that host, store, secure, deliver, or support the Service for us, such as providers of hosting and content delivery, databases and servers, error monitoring, email delivery, analytics, and AI processing. They may use the information only to provide their services to us.
• App stores and payment platforms, such as Apple App Store and Google Play, when you make a purchase.
• Legal and safety reasons, when we believe disclosure is required by law or legal process, or is needed to protect the rights, property, or safety of PRAVIEL, our users, or others.
• Business transfers, if PRAVIEL is involved in a reorganization, financing, merger, acquisition, sale of assets, or transfer to a new legal entity. Information may be transferred as part of that transaction.
• At your direction, when you ask us to share something or choose to make it public.

We do not sell your personal information, and we do not share it with advertisers or data brokers.

We keep information while your account is active and as long as needed for the purposes in this policy, including to meet legal obligations, resolve disputes, prevent abuse, and enforce our agreements.

When you delete your account in the app, we disable it right away and permanently delete the account and its associated app data after a 30-day grace period. Signing in during the grace period cancels the deletion. Limited records may be kept longer where needed for purchases, refunds, fraud prevention, security, or legal reasons.

Backups and logs are deleted on their own schedules. Aggregated or de-identified information may be kept indefinitely.

We use reasonable technical and organizational safeguards designed to protect information, such as encryption in transit, hashed passwords, and restricted access to production systems.

No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

We are based in the United States, and our service providers operate in other countries. Your information may be processed in the United States and elsewhere, where data protection laws may differ from those where you live. Where required, we use appropriate safeguards for these transfers.

Depending on where you live, you may have the right to access, correct, delete, or receive a copy of your personal information, to object to or restrict certain processing, and to withdraw consent at any time without affecting earlier processing.

You can update your profile, turn off personalization and notifications, and delete your account in the app's settings. On our websites, you can change your choices in the privacy controls. For other requests, see the account deletion and data deletion pages, or email privacy@praviel.com from the address linked to your account.

We may need to verify your identity before acting on a request, and we may decline or limit a request where the law allows. If you are in the EEA, the UK, or another place with a data protection authority, you may lodge a complaint with it.

PRAVIEL is not directed to children under 13, and we do not knowingly collect personal information from them. If you are under 18, you may use PRAVIEL only with the permission of a parent or guardian. If we learn that we have collected information from a child under 13, we will delete it. Contact privacy@praviel.com if you believe this has happened.

The controller of your information is Anton Soloviev, doing business as PRAVIEL, in the United States. For privacy questions or requests, email privacy@praviel.com.

Your use of PRAVIEL is also governed by our Terms of Service.

We may change this policy from time to time. We will post the updated version on this page and change the date at the top, and where the law requires, we will give you additional notice, such as in the app or by email. If you keep using the Service after an update takes effect, the updated policy applies to you.

We may translate this policy for convenience. If a translation differs from the English version, the English version controls to the extent the law allows.
