1. Acceptance of Terms

By accessing or using "The Atlas" ("Service", "we", "us", or "our"), you agree to be bound by these Terms of Use ("Terms"). If you disagree with any part of the terms, then you may not access the Service. These Terms apply to all visitors, users, and others who access or use the Service.

Age Limitation: The Service is not intended for individuals under the age of 16. By creating an account, you affirm that you are at least 16 years old. If you are under 18, you affirm that you have parent or guardian permission to use the Service. We do not knowingly collect data from children. If we discover a user is under 16, we will immediately delete the account and all associated data.

2. Beta Service Disclaimer

Please note that the Service is currently in BETA. The Service is provided "AS IS" and "AS AVAILABLE" without any warranties of any kind, either express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, or course of performance.

We do not guarantee that the Service will be stable, uninterrupted, error-free, secure, or reliable. You acknowledge that using the Service may result in unexpected behavior, data loss, or service interruptions. We reserve the right to modify, suspend, or discontinue the Service at any time without prior notice.

3. Accounts and Access

To access the Service, you must register for an account using a valid email address. We verify identities via One-Time Password (OTP) sent to your email.

  • You are responsible for safeguarding the credentials used to access the Service and for any activities or actions under your account.
  • You must notify us immediately upon becoming aware of any breach of security or unauthorized use of your account.
  • You must provide accurate, current, and complete information during the registration process and keep your account information updated.
  • We reserve the strict right to limit the number of accounts created by a single individual or entity. Attempts to bypass these limits (e.g., via VPNs, incognito browsing, browser fingerprint spoofing, or disposable emails) constitutes a material breach of these Terms and will result in immediate account termination.
  • You may not use another user's account without permission.

4. Usage Restrictions and Anti-Abuse

You agree not to engage in any of the following prohibited activities:

  • Scraping: Using any automated system, including without limitation "robots," "spiders," "crawlers," or "offline readers," to access the Service in a manner that sends more request messages to the servers than a human can reasonably produce in the same period of time by using a conventional web browser.
  • Reverse Engineering: Attempting to reverse engineer, decompile, disassemble, or otherwise attempt to discover the source code, object code, or underlying structure, ideas, or algorithms of any portion of the Service or its database structures.
  • Interference: Attempting to interfere with, compromise the system integrity or security, or decipher any transmissions to or from the servers running the Service.
  • Circumvention: Attempting to circumvent any security measures, rate limits, access controls, or anti-abuse systems implemented by the Service.

Account Termination: We may terminate or suspend your account immediately, without prior notice or liability, for any reason whatsoever, including without limitation if you breach the Terms. Upon termination, your right to use the Service will immediately cease. All provisions of the Terms which by their nature should survive termination shall survive, including, without limitation, ownership provisions, warranty disclaimers, indemnity, and limitations of liability.

This limitation applies whether based on warranty, contract, tort (including negligence), strict liability, or any other legal theory, whether or not we have been informed of the possibility of such damage, and even if a remedy set forth herein is found to have failed of its essential purpose.

9. Indemnification

You agree to defend, indemnify, and hold harmless The Atlas and its licensors, employees, contractors, agents, officers, and directors from and against any and all claims, damages, obligations, losses, liabilities, costs or debt, and expenses (including but not limited to attorney's fees), resulting from or arising out of: (a) your use and access of the Service; (b) your violation of any term of these Terms; (c) your violation of any third party right, including without limitation any copyright, property, or privacy right; or (d) any claim that your use of the Service caused damage to a third party.

12. Changes to Terms

We reserve the right, at our sole discretion, to modify or replace these Terms at any time. If a revision is material, we will provide at least 30 days' notice prior to any new terms taking effect (where practical). What constitutes a material change will be determined at our sole discretion.

By continuing to access or use our Service after those revisions become effective, you agree to be bound by the revised terms. If you do not agree to the new terms, you are no longer authorized to use the Service.

13. Severability

If any provision of these Terms is held to be unenforceable or invalid, such provision will be changed and interpreted to accomplish the objectives of such provision to the greatest extent possible under applicable law and the remaining provisions will continue in full force and effect.

14. Waiver

Our failure to enforce any right or provision of these Terms will not be considered a waiver of those rights. The waiver of any such right or provision will be effective only if in writing and signed by a duly authorized representative of The Atlas.

15. Assignment

You may not assign or transfer these Terms, by operation of law or otherwise, without our prior written consent. Any attempt by you to assign or transfer these Terms without such consent will be null and of no effect. We may assign or transfer these Terms, at our sole discretion, without restriction.

18. Force Majeure

The Atlas shall not be liable for any failure or delay in performing its obligations under these Terms if such failure or delay results from circumstances beyond its reasonable control, including but not limited to acts of God, natural disasters, war, terrorism, riots, embargoes, acts of civil or military authorities, fire, floods, accidents, strikes, or shortages of transportation, facilities, fuel, energy, labor, or materials.
