Privacy Policy — HTML Viewer by NexLab

In short: HTML Viewer stores everything locally on your device. We don't collect, transmit, or store any personal data on our servers. The only third-party data collection is by Google AdMob for advertising in the free version. FTP and GitHub credentials are stored encrypted on your device only. Google Drive Sync is coming soon.

1.2 Google Drive Sync

Coming Soon Google Drive Sync

Google Drive Sync is not yet available in this version of the app. This feature is currently under development and will be released in a future update.

When available, it will allow you to open and save HTML files directly from your Google Drive using the drive.file scope only — a restricted permission that grants access solely to files the App itself opens or creates. Your Drive data will never be processed or stored by NexLab.

1.3 FTP & GitHub Sync

FTP server credentials (host, username, password) and GitHub Personal Access Tokens you enter are stored only on your device using encrypted local storage. They are used solely to connect to the server or repository you specify. We do not transmit these credentials to NexLab servers.

1.4 Data Collected by Third Parties

The free version displays ads by Google AdMob, which may collect:

Advertising ID — Resettable device identifier for ad targeting
IP Address — Approximate location (country/region)
Device Info — Model, OS version, screen size
Ad Interaction Data — Impressions, clicks, video completions

See Google's Privacy Policy for full details.

1.5 What We Do NOT Collect

Names, emails, phone numbers, or personal identifiers
Content of your HTML files or code
Browsing history from the built-in browser
Photos, contacts, messages, or data from other apps
No user accounts or registration required
No analytics SDKs (no Firebase Analytics, Mixpanel, etc.)
No AI prompt content is stored — AI requests are processed and discarded immediately

✅ Your HTML files, projects, code snippets, and browsing history stay on your device. We never upload or access your content.

2 AI Assistant Feature

HTML Viewer includes an optional AI assistant that can explain or improve selected code. When you use this feature:

Only the selected code snippet you highlight is sent to the AI service
No file names, project names, or personal data are included in the request
The AI service does not retain your code after generating a response
This feature is only active when you explicitly tap the AI button

⚠️ Do not include sensitive information (passwords, API keys, personal data) in code you send to the AI assistant.

3 Advertising

3.1 Banner Ads

The free version shows banner ads at the bottom of certain screens, served by Google AdMob.

3.2 Rewarded Video Ads

Premium features can be temporarily unlocked by watching rewarded video ads (15–30 seconds). The unlock is session-based and resets when you leave the screen. No personal data is collected by us during this process.

3.3 Opt Out of Personalized Ads

Android: Settings → Google → Ads → Opt out of Ads Personalization
Android 12+: Settings → Privacy → Ads → Delete advertising ID

ℹ️ Opting out doesn't remove ads — they just become less targeted.

3.4 Ad-Free Option

Premium subscribers enjoy a fully ad-free experience with no AdMob data collection.

4 Subscriptions & Payments

HTML Viewer offers optional premium subscriptions. All payments are processed by Google Play Billing. We never see or store credit card numbers, billing addresses, or financial data.

7 Data Security

All user data lives on your device, protected by your device's built-in encryption and screen lock. FTP passwords and GitHub tokens are stored using encrypted local storage. We cannot access your data remotely. Uninstalling the app permanently deletes all stored data.

Network communications (GitHub API, FTP) use HTTPS/FTPS where supported by the server you connect to.

🔒 NexLab has no remote access to your data. Your device's security is your data's security.

8 Data Retention & Deletion

History & bookmarks: Stored until you clear them in Settings
Files & projects: Stored until you delete them
Version history snapshots: Last 10 saves per file, auto-managed
Code snippets: Stored until you delete them
FTP/GitHub credentials: Stored until you remove the connection
Full deletion: Uninstall the app — all data is permanently removed

ℹ️ When Google Drive Sync becomes available, revoking access in your Google Account will remove the app's Drive permissions.

9 Children's Privacy

HTML Viewer is not directed at children under 13. We do not knowingly collect information from children. Ads comply with Google's child-directed treatment policies.

10 International Users

We don't transfer personal data across borders. Google AdMob follows GDPR-compliant data processing for EEA users. GitHub complies with applicable international privacy frameworks.

11 Your Rights

Access: All data is on your device — you always have full access
Delete: Clear history in Settings, delete files, or uninstall the app
Opt-out of ads: Disable personalised ads via device settings
Remove GitHub access: GitHub Settings → Applications → Authorised → Revoke
Portability: HTML files are standard — copy and share freely
Permissions: Revoke any app permission anytime in device Settings

12 Policy Changes

We may update this policy for legal or operational reasons. The "Last updated" date will change. Continued use after updates means acceptance.

Significant changes affecting third-party account access or data handling will be communicated via an in-app notice or app store update notes.
