About this policy
This policy covers the Verbilo app and verbilo.app. Verbilo supports language learning through reading, listening and practice. It describes currently available features; we will update it when new platforms or features change how we use data.
Contact the Verbilo team using the email below for privacy questions and data requests.
Information we use
On your device: downloaded stories, reading preferences and position, saved words, reviews, quiz answers and practice results. These support your learning progress and offline use where available.
When you create an account or sign in: we receive information such as your name, email and account identifier from Google/Firebase, and keep session information to protect access. We do not receive your Google password. Password-based Verbilo accounts store a secure password hash.
When you use cloud features: we store account information, generated stories and generation requests, and upload learning records when you use sync. We may also process support messages you send and the contact details needed to reply.
AI and microphone features
To generate a story, we send your chosen level, topic, interests and practice words to OpenAI. For sentence help, we send the selected sentence and requested help type. We store the results to provide them to you.
The microphone is used when you grant permission and start practice. Sentence recordings are uploaded when you request an assessment; continuous reading practice streams audio during the session you start. Microsoft Azure processes audio for transcription and pronunciation results. Verbilo does not keep practice recordings as permanent server files; transcripts and results may be saved in your practice history.
Temporary sentence recordings on your device are deleted when you leave practice, or on the next app launch after an interruption. Cloud narration sends story text to Azure and may cache the generated audio. An installed device voice may need its provider’s internet connection. Providers process and retain data under their own settings and terms.
Analytics and crash reports
The app uses Firebase Analytics to understand feature use and Firebase Crashlytics to diagnose crashes. Both are enabled by default and may collect app activity, installation identifiers, device information, technical diagnostics and approximate location inferred from connection data such as IP address. The app does not request precise GPS location.
Our custom events do not include names, emails, story text, selected words, answers, pronunciation results or recordings. We do not use the Advertising ID or ad personalization.
You can switch each off under Settings → Account & sync → Privacy & your data. Full crash-report opt-out takes effect on the next launch. These settings apply to the device and do not delete reports already sent. Re-enabling reports may send crash information retained locally.
Purchases and subscriptions
Where purchases are available, Google Play handles payment. Verbilo receives the product identifier, purchase token and subscription status to verify paid access. We do not receive your payment-card details.
Deleting your Verbilo account does not automatically cancel a Google Play subscription. Cancel it through Google Play’s subscription settings. Google Play may also check for app updates and download and install them with your approval.
Services that help run Verbilo
We use Hetzner for hosting, Cloudflare for website protection and delivery, Google/Firebase for accounts, analytics, crash reports and store services, OpenAI for content generation and explanations, and Microsoft Azure for voice features. Each receives information needed for its function as described above.
These services may process data outside your country. Our website and security services receive connection information such as IP address, browser and request details. Necessary security cookies may be used; the administration area uses cookies for administrator sign-in. We do not sell your personal data.
Security and retention
We use HTTPS, account and administrator access controls, and protected device storage for sign-in tokens. No storage or transmission method is completely risk-free.
We keep cloud account and learning data while needed to provide the service, or until you delete the data or account. Rotating backups expire within eight days. Limited security and administrative records may remain after deletion to protect the service, investigate abuse or meet legal obligations.
Provider retention depends on the service, settings and applicable terms. Deleting a Verbilo account does not delete device-based analytics and crash reports already submitted.
Export data and delete your account
In the app, open Settings → Account & sync. You can export learning data, or select Delete account and complete the identity confirmation. Deletion removes your Verbilo account and associated records from the active database, including personal stories, learning history and sessions, and removes the current account’s local data.
If you cannot use the app, email the support address below from your account email with the subject “Delete my Verbilo account”. We need to verify account ownership before acting. Do not send passwords or sign-in codes. You can also request access to or correction of your information.
This does not delete your Google account. Backup copies may remain for up to eight days, and limited records may remain as explained above. You need to remove exported files and downloads on other devices yourself. Signing out alone does not delete learning data.
