This policy explains what Vocarium collects when you use the app, why we collect it, who we share it with, and the choices you have. Vocarium is a vocabulary review and flashcard app. By creating an account or using Vocarium without an account you agree to the practices below.
Vocarium is operated by the Vocarium team. If you have any question about this policy, your data, or a request about your rights, write to us at hello@vocarium.app. We answer data requests within 30 days.
Guest mode: if you use Vocarium without an account, your folders, sets and study history are stored only in your browser's local storage on that device. We do not receive them until you create an account and choose to move them to the cloud.
We never sell your personal data. We share it only with service providers that help us run Vocarium, and only for that purpose:
Content you deliberately publish — a set shared to Media, a public profile, a shared link, or a creator page — is visible to other users or to anyone with the link. Do not put private or sensitive information into shared content.
We use local storage and cookies that are strictly necessary to keep you signed in and to remember your preferences (theme, study settings, guest data). We may also use analytics and advertising cookies or identifiers. Where consent is required, we ask for it through a consent banner before any non-essential cookie is set, and you can change your choice at any time.
Vocarium is free to use and may show advertising inside the app, including banner and in-content formats. Advertising may be delivered by third-party ad networks and measurement partners.
Our providers may process data outside your country, including in the United States and the European Union. When data leaves the EEA/UK/Türkiye we rely on appropriate safeguards such as the European Commission's standard contractual clauses.
Depending on where you live (GDPR, UK GDPR, Türkiye's KVKK, CCPA and similar laws) you can request access to your data, correction, deletion, a portable copy, restriction of or objection to processing, and withdrawal of consent. Most of this is available directly in Settings; for anything else write to hello@vocarium.app. You also have the right to complain to your local data protection authority.
Vocarium is not intended for children under 13 (or under the minimum age in your country, such as 16 in parts of the EEA) without the consent of a parent or guardian. If we learn that we hold data from a child without valid consent, we delete it.
Data is transmitted over encrypted connections and stored with row-level access rules so that only you (and people you share with) can reach your content. Passwords are hashed. No system is perfectly secure, so please use a strong, unique password.
If we make a material change we will update the date at the top and notify you in the app or by e-mail before the change takes effect.

Vocarium is operated by Babur Aydogan, who is the data controller for the data described in this policy.
Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. When you buy a subscription, your name, email address, billing address, tax details and payment method are collected and processed directly by Paddle — we never see or store your card details. Paddle uses that data to take payment, manage your subscription, issue invoices, meet tax obligations, prevent fraud and handle refunds.
Paddle passes back to us only what we need to link the subscription to your account: subscription and customer identifiers, plan, status and billing period dates.
