Our service is provided free of charge and is supported through advertising revenue. We reserve the right to modify, suspend, or discontinue any part of our service at any time.

You are responsible for ensuring your content does not infringe upon third-party rights. We reserve the right to remove content that violates these Terms or applicable laws.

By using ERDPlus, you consent to the collection and use of information as described in our Privacy Policy. We implement appropriate security measures to protect your data.

ERDPlus is a free service supported by advertising revenue. We may display third-party advertisements on our platform.

We do not endorse or guarantee any products, services, or content that appear in advertisements. Your interactions with advertisers are solely between you and the advertiser.

We are not responsible for the content, privacy policies, or practices of third-party websites or services that may be linked to or from ERDPlus.

ERDPlus is provided "as is" and "as available" without warranties of any kind. We make no guarantees that the service will be uninterrupted, error-free, or meet your requirements.

We do not warrant that our service will be free from viruses, malware, or other harmful components. You use ERDPlus at your own risk.

We may perform maintenance, updates, or modifications to the service at any time, which may temporarily affect availability.

To the maximum extent permitted by law, ERDPlus shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, or use, arising from your use of our service.

Some jurisdictions do not allow the limitation of liability, so these limitations may not apply to you.

We may terminate or suspend your account and access to our service immediately, without prior notice, for any reason, including if you breach these Terms.

You may terminate your account at any time by contacting us. Upon termination, your right to use the service will cease immediately.

Provisions of these Terms that by their nature should survive termination shall survive, including ownership provisions, warranty disclaimers, and limitations of liability.

These Terms are governed by the laws of the United States (State of Delaware), without regard to conflicts of law principles. They apply to all users worldwide, but any dispute must be resolved under Delaware law.

Disputes will be resolved first through good-faith negotiation. If unresolved, they will be settled by binding arbitration in Delaware, unless arbitration is not permitted by law, in which case disputes will be handled in Delaware courts.

You agree to waive any right to participate in a class action lawsuit or class-wide arbitration against ERDPlus.

We may update these Terms from time to time. We will notify users of material changes through our website or by email.

Continued use of ERDPlus after changes to these Terms means you accept the updated Terms. If you do not agree to the updated Terms, you must stop using our service.

If any provision of these Terms is found to be unenforceable or invalid, the remaining provisions will remain in full force and effect.
