DISCLAIMER: We are not attorneys and do not offer legal advice. Laws vary by country and platform. For any legal question please consult a qualified legal professional.

We give you full control over download speeds because we believe users should decide how they use their software.

That said, here are a few widely accepted best practices for safe, responsible downloading:

1. Only download content you created, own, or have explicit permission from the rights holder to access.
2. Protect your personal data by respecting platform rules and rate limits with reasonable download speeds to avoid automated abuse systems putting your account at risk.
3. Protect your privacy by using a reputable VPN for IP protection before initiating downloads — this is the VPN we recommend & use.
