Privacy policy

1. Who we are

Typoholic ("we", "us", "our") is a language-learning web app and service available at typoholic.xyz and through its companion applications. This Privacy Policy explains what information we collect when you use Typoholic, why we collect it, how we keep it safe, and the rights you have over it.

We are the data controller for the personal information described in this policy. If you have a question, a complaint, or a request, write to us at the contact address shown at the end of this document. We aim to answer every privacy request within thirty days.

2. Information we collect

We collect the minimum amount of information needed to run the service. In practice, this means the following:

Account information. When you sign in, we store your email address and a secure identifier for your account. We never store your password in a readable form; authentication is handled through secure, industry-standard flows (email magic links or trusted identity providers).

Learning progress. To make Typoholic work at all, we must store your learning data: the lessons you complete, your answers to exercises, your mistakes, the words you have practiced, your daily usage, your chosen language pair, your settings and preferences, and the scores and history we calculate from that activity. This data is the core of the service: without it, the app cannot adapt to you, remember your mistakes, or show you your progress.

Text you bring in. If you paste your own text into the app to turn it into a lesson, those texts are processed to build your lesson and may be retained as part of your learning history so that you can return to them.

Technical and usage data. Like most web services, our servers and log systems record basic technical events: dates and times of requests, page and feature identifiers, error messages, the type of browser and device you use, and your approximate region derived from your IP address. We use this to keep the service running, to find and fix bugs, and to protect against abuse.

Cached translations. To make the service fast and affordable, translated sentences and AI-generated lesson content are stored in a shared cache on our servers. The cache stores the source text and its translation, not your identity, and it is reused for the benefit of all users.

3. What we do with your information

We use your information for exactly four purposes:

To provide the service you asked for. Your learning progress, answers, and preferences are used to build your lessons, adapt content to your level, keep your scores, and resume where you left off.

To improve the product. Aggregated and anonymized patterns help us understand where lessons are too hard, where translations fail, and where the app breaks. We analyze usage in bulk, not per-individual, unless we are fixing a specific problem you reported.

To communicate with you. If you choose to receive them, we send emails about your progress, reminders, and occasionally about the product. You can disable these at any time from your settings or with the unsubscribe link in every email.

To keep the service safe. We monitor for abuse, fraud, spam, and behavior that violates our terms, and we may temporarily or permanently block accounts that engage in it.

4. What we never do

Some things are easier to state plainly than to bury in paragraphs:

We do not sell your personal information. Not now, not ever. There is no mechanism in our system that transfers your data to a buyer for money.

We do not share your learning data with other users. Your lessons, mistakes, and scores are private to you unless you deliberately share them yourself, for example by sending someone a link to your results.

We do not advertise to you using your learning content. We do not build advertising profiles from the sentences you read or the words you miss.

We do not require you to hand over more data than the service needs. You can try Typoholic and read and practice without creating an account, and your free plan is a real plan, not a trial that secretly collects more later.

5. Where your data lives and how it is protected

Your data is stored on servers we control or that our hosting partners operate for us, using industry-standard access controls, encryption in transit (TLS), and encrypted storage where it is feasible. Access to production systems is restricted to the people who need it to run them, and every access is logged.

No internet service is perfectly secure. We cannot promise absolute security, and we encourage you to use a strong, unique password for any account you create and to keep your email account safe, since email-based sign-in depends on it.

If a breach affects your personal information, we will notify you and the relevant authorities in line with applicable law, and we will tell you what happened and what we are doing about it.

6. Retention

We keep your learning data for as long as your account exists, because that history is the product: your progress, your locked-in words, and your scores are what you came back for.

You can delete your account and your data at any time by contacting us or using the deletion option in your settings. When you ask for deletion, we remove your account information, your learning history, and your personally identifiable data from our systems within a reasonable period, and we stop any further processing. Some anonymized, non-identifiable data may remain for research and legal purposes, and we may keep records where the law requires us to do so.

If you do not use the service for a long period, we may eventually delete or anonymize your account data, and we will warn you before we do.

7. Cookies and similar technologies

Typoholic uses cookies and browser storage (localStorage) to keep you signed in, to remember your session, and to make the page load safely. We also use standard analytics and marketing pixels (such as Meta’s pixel) to measure how our marketing performs and to understand which pages people visit, so we can improve them.

You can block or clear cookies through your browser at any time. Blocking them may sign you out more often or disable some conveniences, but it will not prevent you from learning.

8. Children

Typoholic is a general-audience learning tool. If you are under the age required by your country to consent to online services (13 in many places, sometimes older), please use Typoholic only with the involvement of a parent or guardian, and ask them to help you understand this policy.

If we learn that we have collected personal information from a child below the applicable age without parental consent, we will delete it promptly. Contact us if you believe this has happened.

9. Your rights

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

Access the personal information we hold about you.

Correct inaccurate information (your settings already let you fix much of it yourself).

Request deletion of your data and account.

Restrict or object to certain processing.

Export a copy of your data in a portable, readable format.

Withdraw consent where processing is based on consent.

Send privacy-related requests to the contact address below. We will respond within the time the law allows, and we will never penalize you for exercising these rights.

If you are in the European Union or the UK, you also have the right to lodge a complaint with your local data-protection authority.

10. Third-party services

Typoholic relies on trusted third-party providers for parts of its infrastructure (hosting, database services, email delivery, and AI/translation services that help create and translate lesson content). These providers process data only to provide the service to us, under contracts that require them to protect it. Some AI content generation may involve sending the text you are learning to a third-party model provider; that text is used to generate your lesson and is not used to train those models for other purposes, to the extent the provider permits.

When you click a link to another site, their own privacy policies apply from that moment on.

11. Changes to this policy

We may update this policy as the service evolves. We will post the new version here and update its date. If a change is significant, we will make it obvious in the app or by email. Continued use of Typoholic after a change means you accept the updated policy as it applies to data collected from that point forward.

12. Contact

Questions about this policy, about your data, or about exercising your rights can be sent to the email address shown in the app’s About screen or through the support contact in your settings. We read every message and answer as quickly as we can.
