Privacy Policy

Effective date: October 10, 2026

Lavna is an app for practicing thinking skills. It is made by Sololearn Inc. (“Sololearn”, “we”, “us”). This policy explains what personal data we collect when you use the Lavna apps for iOS and Android, the Lavna web app, shared practice links and the lavna.app website (together, “Lavna”), why we collect it, who we share it with, and the choices you have.

The short version

• We collect what we need to run Lavna: your account, your practice answers and progress, and what you choose to post.
• Other Lavna users can see your profile name, photo, practice stats and comments. They can’t see your email address.
• We don’t sell your data.
• We don’t send your answers, comments or other personal data to AI companies.
• You can delete your account in the app at any time. We delete it right away.

The rest of this policy gives the details.

1. Who we are

Sololearn Inc., 1521 Alton Rd, #247, Miami Beach, Florida 33139, USA, is responsible for your personal data (the “controller”). You can reach us at data.privacy@lavna.app.

2. What we collect

2.1 Data you give us

• Account. How you sign in decides what we get:
  • Email: your email address. We email you a one-time code to sign in. There are no passwords.
  • Apple: your name (Apple shares it only the first time) and an email address. If you choose “Hide My Email”, we get a private relay address from Apple, not your real address.
  • Google: your name, email address and profile photo.
  • Guest: nothing. We create an anonymous account with a random ID.
• Profile. Your display name, your profile photo if you add one, and your profile theme. If you don’t choose a name or photo, we give you a starting name (like “Curious Thinker”) and a picture. If you sign in with Apple or Google, we may use the name and photo they share to start your profile. You can change them at any time.
• Onboarding answers. When you start Lavna, we ask about your goal and how important it is to you, your daily goal, the skills you’re good at and the ones you want to improve, your age range (for example “25-44”), what describes you best (for example student or parent), and your name and reminder time. We save the answers as you go, even if you don’t finish.
• Practice answers. The answers you give, whether they were right, and when.
• Comments you post on practices, and your edits.
• Reports and blocks. When you report a comment or a profile: the reason, your note if you write one, and a copy of what you reported. When you block someone: who you blocked.
• Searches for a skill we don’t have yet, so we know what people want.
• Messages you send us, for example by email to support.

2.2 Data we create as you use Lavna

• Progress: XP, levels, streaks, daily goal history, achievements, your energy balance and its history, the practices you liked, and a count of your shares. We don’t see where you share.
• Lavna Pro purchases. Apple or Google handles the payment. We never see your card or payment details. We receive and keep: the plan, whether you are in a free trial, whether it renews, the renewal or end date, and the store’s ID for the purchase. When you buy, we give the store your Lavna account ID (a random code), so the purchase goes to the right account.
• Age range from Apple or Google. Where your app store shares it, we receive your age range (13-15, 16-17 or 18+). We keep only that range, the date and which store it came from. We use it only to check that Lavna is right for your age and to follow the law, never for ads, analytics or profiling.
• Device and technical data: your device’s time zone (so streaks, daily goals and reminders follow your local day), your platform (iOS, Android or web), and a push notification token if you allow notifications. Our servers record your IP address and the pages and features you request, and our sign-in provider records sign-in events, for security.
• Crash and error reports. When the app crashes or hits an error, it sends a report to our crash reporting provider: what went wrong and where in our code, the screens you opened and the app’s last actions before the problem (taps and calls to our servers), your device model, operating system and app version, and your Lavna account ID. Reports don’t include your name, email, IP address, location, comments or answers. The app also tells our crash reporting provider when you open it and whether that session ended in a crash, so we can see how stable each version is. You can turn all of this off in Settings, Share usage and diagnostics.
• Settings groups. We may place your account in a group with different settings, for example a different energy limit, to learn what works best.
• Moderation records. If we act on your content or account (for example, remove a comment or stop you from commenting), we keep a record of what we did and why.

2.3 Shared practice links

Anyone can open a shared practice link in a web browser and play without an account. We don’t store those answers, with one exception: for “estimate” questions, we store the guess together with a random ID saved in that browser, so each browser counts once in the crowd results. This is not linked to any person or account.

2.4 What we don’t collect

• We don’t collect your precise location, contacts, health data, or recordings from your camera or microphone.
• We only access your photo library when you choose a profile photo, and only the photo you pick. We remove hidden information from photos when you upload them, such as the place where the photo was taken.
• We don’t collect payment card details.

3. How we use your data

Automated decisions. We don’t make decisions about you that have legal or similarly significant effects by automated means only. Two things are automatic: a word filter blocks some words and all links in comments and names, and when two people report the same comment or profile, we hide it until a person on our team reviews it. People make every decision on reports.

4. Artificial intelligence

Many Lavna practices are created with the help of AI tools. Our team reviews them before they are published. We don’t send your answers, comments, profile or any other personal data to AI providers, and we don’t use your personal data to train AI models. If this changes, we will update this policy first.

5. What other users can see

• Your profile: display name, photo, the month you joined, your streak, number of practices, accuracy, level, XP, skills and their levels, achievements, whether you have Lavna Pro, and your profile theme if you have Pro. Your email address is never shown.
• Your comments: with your name and photo, to everyone who opens that practice in Lavna, including guests.
• Any Lavna user can open your profile by tapping your name on a comment, or with your profile ID. Profiles are only visible inside Lavna, not on the public web.
• Likes and shares show as totals only. The practices you like are saved to a list only you can see.
• If you block someone, you and that person no longer see each other’s comments or profiles. They are not told.
• You can change your name and photo, and edit or delete your comments, at any time.

6. Who we share data with

We don’t sell your personal data.

Service providers. Companies that host our servers and database (including sign-in and profile photos), send sign-in code emails, deliver push notifications, and collect crash and error reports. They process data for us under contracts that limit what they can do with it.

Apple and Google. When you sign in with Apple or Google, or buy Lavna Pro through the App Store or Google Play, they process your data under their own privacy policies.

Other users. As described in section 5.

Our team. Sololearn staff who work on Lavna can see account data when they need it: to help you, review reports, and run and fix the service.

Legal reasons. We share data when the law requires it, or when we believe in good faith it is needed to protect the safety, rights or property of our users, the public or Sololearn.

Business changes. If Sololearn is part of a merger, acquisition or sale of assets, your data may move to the new owner. This policy will keep applying to it, and we will tell you before that changes.

With your permission. In any other case, only if you agree.

7. International transfers

We store your data in the United States (Oregon). If you live outside the US, your data moves to the US, where data protection laws may differ from yours. For data from the European Economic Area, the United Kingdom and Switzerland, we rely on the European Commission’s Standard Contractual Clauses, with the UK Addendum and the Swiss amendments. You can ask us for a copy of these safeguards.

8. How long we keep data

• Account data, profile, progress, onboarding answers and comments: as long as your account exists.
• When you delete your account: we delete it from our systems right away, including your profile photos, comments, answers, reports and blocks. Copies in our backups disappear as the backups expire, within 30 days.
• Guest accounts: we delete a guest account and its data after 12 months without use. If you sign out of a guest account, you can’t get back into it, so delete it in Settings first if you want its data gone now.
• Comments removed by moderation: kept with your account, so we can review appeals and repeat abuse, until the account is deleted.
• Server and sign-in logs: up to 30 days.
• Crash and error reports: 90 days, also after you delete your account.
• Estimate guesses from shared links: kept as part of the crowd results. They are not linked to any person.
• Purchases: Apple and Google keep their own records under their policies.

9. Security

We protect your data with encryption in transit (HTTPS), access controls, and by limiting who on our team can see personal data. No system is perfectly secure, so we can’t promise that your data will never be accessed without permission. If a breach affects you, we will tell you as the law requires.

10. Your choices and rights

10.1 In the app

• Profile: change your name and photo in Edit profile.
• Notifications: turn reminders on or off in the app, or turn off notifications for Lavna in your device settings.
• Crash and error reports: in Settings, turn off Share usage and diagnostics, and the app stops sending them.
• Blocking: block users from a comment or a profile. Manage the list in Settings, Blocked users.
• Delete your account: Settings, Delete account. This works for guest accounts too. Deleting your account does not cancel Lavna Pro: cancel it in the App Store or Google Play first.
• Without the app: follow the steps on our Delete your account page.

10.2 Your rights

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

• get a copy of your personal data, including in a format you can move to another service;
• correct data that is wrong;
• delete your data;
• object to, or ask us to limit, how we use your data;
• withdraw consent at any time, where we rely on consent (this doesn’t affect what we did before);
• complain to your local data protection authority.

In the EEA, UK and Switzerland you have all of the rights above. You can object at any time to uses based on our legitimate interests. You can find your data protection authority at edpb.europa.eu (EEA), ico.org.uk (UK) or edoeb.admin.ch (Switzerland).

In US states with privacy laws (including California, Colorado, Connecticut, Virginia, Texas and Oregon) you have the right to know what we collect, access it, correct it, delete it and get a copy. You also have the right to opt out of the sale of your data, of sharing it for targeted advertising, and of profiling with significant effects. We don’t do any of these. We won’t treat you differently for using your rights. If we deny your request, you can appeal by replying to our answer; if you still disagree, you can contact your state attorney general.

In Brazil you have the rights under the LGPD (Lei Geral de Proteção de Dados), including to confirm that we process your data and to access, correct, anonymize, move or delete it. Our contact for LGPD requests is data.privacy@lavna.app.

10.3 How to make a request

Email data.privacy@lavna.app from the email address on your Lavna account. For a guest account, include your profile ID (Settings shows it). To protect you, we check that the request comes from the account owner before we act. You can also use an authorized agent; we will ask for proof that they act for you. We answer within 30 days (45 days in US states where the law allows), and tell you if we need more time.

11. Notice for California residents

In the last 12 months we collected these categories of personal information, from you, your device, and Apple or Google when you sign in with them:

We use this information for the purposes in section 3, keep it as described in section 8, and disclose it for business purposes to the service providers in section 6. We don’t sell or share personal information (as these words are defined in California law), and we don’t collect sensitive personal information. We have no actual knowledge of selling or sharing data of people under 16.

12. Children

Lavna is not for children under 13, or under the higher minimum age in your country. Where Apple or Google can tell apps your age range (for example, where the law requires it), we check it when you start Lavna and don’t let anyone under 13 use it. We don’t knowingly collect personal data from children under 13. If you believe a child has given us personal data, email data.privacy@lavna.app and we will delete it.

13. The lavna.app website

Our hosting provider records IP addresses in server logs for security. The Lavna web app stores your sign-in session in your browser (and, on shared links, the random ID described in section 2.3). These are needed for Lavna to work, and you can remove them by clearing your browser’s site data.

14. Changes to this policy

When we update this policy, we change the effective date at the top. If a change is important, we will tell you in the app or by email before it takes effect.
