Learn words from the books you read.

Information We Collect

Gloss collects information needed to provide your vocabulary learning account and features.

• Account information: your email address and, if you sign in with Google, account details made available for authentication, such as your name and email address.
• Learning information: saved words, definitions and examples saved with words, review history, mastery progress, streaks, achievements, and daily goal settings.
• Scan information: book page images you choose to capture or select, and text detected from those pages, when you use the scan feature.
• Device-stored information: recent scan images and detected text, onboarding status, and local reminder preferences.

How We Use Information

We use information to create and authenticate your account, recognize text in selected page images, show definitions, save vocabulary, schedule reviews, calculate learning progress, display achievements, manage reminders, provide support, protect the service, and process an account deletion request.

Gloss does not include advertising or third-party tracking features, and we do not sell your personal information.

Scans And OCR

When you scan or select a book page, Gloss resizes the image on your device and sends it through an authenticated Supabase Edge Function to Google Cloud Vision for text recognition. The recognized text and word positions are returned to the app so you can tap words.

Gloss does not save page images in its server database or Supabase Storage. For convenience, your four most recent scan images and their detected text may remain in the app's local storage on your device. You can remove a recent scan in the scan tab. This local history is also cleared when you sign out or delete your account.

Images processed by Google Cloud Vision are handled by Google as a service provider under its applicable terms and privacy practices.

Sharing And Service Providers

We disclose data only as needed to operate Gloss, respond to lawful requests, protect rights and safety, or with your direction. Current service providers and integrations include:

• Supabase, for authentication, database storage, and server functions.
• Google Cloud Vision, for OCR processing of page images you submit.
• FreeDictionaryAPI, for word definition lookups; a word you look up is sent to retrieve its definition.
• Google, if you choose Google sign-in, to complete authentication.
• Apple and Google device services, when you grant app permissions or schedule local notifications through your device.

Retention And Deletion

Your account and learning information are retained while you maintain a Gloss account so that your vocabulary and progress remain available. Recent scan images are kept locally on your device only in a rotating history of up to four scans, unless removed earlier or cleared by the operating system.

You can permanently delete your account in Profile under Delete account. Deleting your account removes your account and associated server-stored vocabulary, settings, review progress, and achievements, and clears local scan history on that device. Some information may be retained only when required for security, legal, or compliance obligations.

Permissions And Choices

Gloss asks for camera or photo library access only when you choose to scan a page or select an image. Notification permission is requested only if you enable a daily reminder. You can change these permissions in your device settings and turn reminders off from within the app.

You can choose not to scan pages, delete individual recent scans, remove saved words, sign out, or delete your account.

Security

Gloss uses authenticated requests and Supabase row-level security intended to restrict account data to its owner. On supported native devices, authentication sessions are stored using secure device storage. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

Children's Privacy

Gloss is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, please contact us so it can be addressed.

Changes To This Policy

We may update this Privacy Policy as Gloss changes. If we make material changes, we will update the effective date and provide notice where appropriate.

For privacy questions or requests, contact the Gloss developer using the support contact listed on the App Store or Google Play listing for the app.

Using Gloss

Gloss is a vocabulary learning app that helps you scan pages, look up words, save vocabulary, and review words over time. You may use Gloss only if you can form a binding agreement and comply with these terms and applicable laws.

You are responsible for the activity on your account and for keeping your sign-in credentials secure.

Your Content

You keep ownership of the page images you choose to scan and the vocabulary content you save in Gloss. You give Gloss permission to process that content only as needed to provide the app, including OCR, dictionary lookup, storage, review scheduling, support, security, and account deletion features.

You are responsible for having the right to scan or upload any page image or content you submit to Gloss.

Acceptable Use

Please use Gloss in a lawful and respectful way. You agree not to:

• Use Gloss to violate anyone's rights or applicable law.
• Attempt to access another user's account or data.
• Interfere with, abuse, reverse engineer, or disrupt the app, backend, OCR pipeline, or related services.
• Submit malicious code, automated abuse, or content you do not have permission to use.

Third-Party Services

Gloss relies on service providers and integrations such as Supabase, Google Cloud Vision, FreeDictionaryAPI, Google sign-in, Apple platform services, and device notification services. Their own terms and privacy practices may apply when you use features powered by them.

Learning Content

Definitions, examples, OCR results, review schedules, and progress information are provided for learning and convenience. They may be incomplete or inaccurate, and Gloss is not a professional, legal, academic, or linguistic advice service.

Account Deletion And Changes

You can delete your account from Profile in the app. Account deletion permanently removes your account and associated server-stored vocabulary, settings, review progress, and achievements, and clears local scan history on that device.

We may change, suspend, or discontinue parts of Gloss as the app evolves. We may also suspend or terminate access if an account is used in a way that violates these terms or creates risk for Gloss, other users, or service providers.

Disclaimers

Gloss is provided "as is" and "as available" without warranties of any kind, to the fullest extent permitted by law. We do not guarantee that Gloss will always be available, error-free, secure, or that learning results will meet your expectations.

Limitation Of Liability

To the fullest extent permitted by law, Gloss and its developer will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost data, profits, or goodwill arising from your use of the app.

Updates To These Terms

We may update these Terms of Service as Gloss changes. If we make material changes, we will update the effective date and provide notice where appropriate. Continuing to use Gloss after changes take effect means you accept the updated terms.
