Terms of Service

Last updated: November 2026

The service

blackdroid.dev provides a collection of free online developer tools, including client-side utilities that run in your browser and hosted services such as Watchdroid uptime monitoring and the Mail Blackhole fake SMTP service.

Accounts

Some features require sign-in via Google or GitHub OAuth. You are responsible for the activity that happens under your account and for keeping access to your OAuth provider account secure. We may suspend or remove accounts that violate these terms.

Acceptable use

You agree not to use the service to:

• Send, store or relay spam, phishing, malware or other abusive content — including through Mail Blackhole mailboxes and monitored endpoints.
• Monitor, probe or attack systems you do not own or are not authorized to test.
• Attempt to bypass rate limits, quotas or access controls, or to disrupt the service for other users.
• Use the service for anything unlawful.

Your content

Data you store in hosted features (monitors, mailboxes, messages) remains yours. We do not claim ownership of it, but you grant us the right to store and process it as needed to operate the service. Email received by Mail Blackhole mailboxes is automatically deleted after a retention period, and other stored data may be removed if your account is deleted.

Availability & changes

The service is provided free of charge on a best-effort basis. We do not guarantee uptime, monitoring accuracy or notification delivery — do not rely on blackdroid.dev as your sole alerting or mail delivery channel. Features may change or be discontinued at any time.

Disclaimer of warranty

The service is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement.

Limitation of liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, consequential or special damages — including lost data, lost profits or missed alerts — arising from the use or inability to use the service.

Third-party services

The service relies on third parties such as Google (sign-in, ads), GitHub (sign-in) and AI model providers. Their terms apply to your use of those integrations; see the Privacy Policy for details on data handling.

Changes to these terms

We may update these terms from time to time. Continued use of the service after changes are posted constitutes acceptance of the new terms.
