1. Agreement
These Terms of Use (the "Terms") govern your use of the BitFlowSim website at bitflowsim.com, the web application at app.bitflowsim.com, and related services (together, the "Service"). By creating an account or otherwise using the Service, you agree to these Terms and to the documents they incorporate: the Subscription and Billing Terms. Acceptable use and copyright reporting are included below. Our Privacy Notice explains how we handle personal information.
If you do not agree to these Terms, do not use the Service.
2. Who we are
The Service is operated by Carlos Garcia, an individual doing business as BitFlowSim as a sole proprietor in Puerto Rico ("we," "us," or "our"). You can reach us at simplc5000@gmail.com.
3. Eligibility
- You must have reached the age of majority where you live and be able to enter a binding contract. In Puerto Rico, the age of majority is 21.
- The Service is currently for adults only. Guardian permission does not make a minor eligible.
- Adults may use their own individual accounts in a classroom. We do not currently offer school-managed accounts or institutional agreements.
- You may not use the Service if barred by applicable law or if we previously terminated your account for violating these Terms.
4. Your account
- Give accurate information when you register and keep your email address current.
- Keep your password confidential. You are responsible for activity under your account. Tell us promptly at simplc5000@gmail.com if you believe your account has been accessed without permission.
- Accounts are for one person. You may not share, sell, or transfer your account or its subscription.
5. Using the service
Subject to these Terms and your plan, we grant you a limited, personal, non-exclusive, non-transferable, revocable right to access and use the Service for learning, teaching, and personal or professional practice. You must follow the acceptable-use rules below. We may change, add, or remove features and adjust usage limits, subject to applicable law and any specific commitments we make to you.
6. Your projects and content
You keep ownership of the ladder programs, tags, project names, descriptions, and other material you create in or upload to the Service ("Your Content"). You give us a worldwide, non-exclusive, royalty-free license to host, store, copy, process, and display Your Content only as needed to operate, secure, and support the Service for you. This license ends when Your Content is deleted from our systems, except for copies kept in backups for a limited time or as required by law.
You are responsible for Your Content and confirm that you have the rights needed to use it in the Service. Do not upload programs, documentation, or other material that belongs to an employer, client, or vendor unless you are authorized to do so. We do not review Your Content routinely, but we may remove content that we reasonably believe violates these Terms or the law.
Keep your own copies of anything important. The Service is not a backup system, and we do not guarantee that Your Content will never be lost.
7. Plans and payment
Access is currently by invitation, without payment. Paid subscriptions are not available. Published paid plans are proposed plans, not an offer to charge you now. See the Subscription and Billing Terms for the current status.
8. Training simulator only
BitFlowSim is educational software. It simulates ladder logic in your web browser and does not connect to or control any physical programmable logic controller, input/output device, machine, or process.
- The simulator is a simplified model. Its behavior, timing, and instruction set may differ from any vendor's controller, firmware, or programming software, and we do not guarantee that a program that works in the simulator will work, or work safely, on real equipment.
- Do not use the Service, or programs developed or tested in it, to design, commission, validate, or operate production systems, safety systems, or any equipment where a failure could cause injury, death, property damage, or environmental harm.
- The Service does not provide professional engineering advice, certification, or proof of competency. Always follow applicable codes, standards, manufacturer documentation, and the direction of qualified personnel when working with real control systems.
The Service is independently developed and is not affiliated with, endorsed by, or certified by any PLC vendor. It does not open, import, or export any vendor's proprietary project files.
9. Our intellectual property
The Service, including its software, simulator engine, design, text, graphics, and the BitFlowSim name and logo, belongs to us or our licensors and is protected by law. Except for the limited right in section 5, these Terms do not give you any rights in the Service. If you send us suggestions or feedback, we may use them without any obligation to you.
10. Third-party services
We rely on third-party providers for hosting, databases, email delivery, and bot protection, as listed in the Privacy Notice. We are not responsible for third-party websites or services that the Service links to.
11. Suspension, termination, and deletion
- You may stop using the Service at any time. You can delete your account from the Account page in the app. Deleting your account permanently removes your projects and account data as described in the Privacy Notice. There is currently no paid subscription to cancel.
- We may suspend or terminate your access, with notice when reasonably possible, if you materially or repeatedly violate these Terms, if required by law, or to protect the Service, other users, or the public.
- We may discontinue the Service. If we do, we will give at least 30 days' notice by email when possible, so you can export or copy Your Content, subject to any legal or security restrictions.
- Sections that by their nature should survive termination, including the last two paragraphs of section 6 and sections 8, 9, and 12 through 17, survive.
12. Disclaimers
To the fullest extent permitted by law, the Service is provided "as is" and "as available," without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure, or that simulation results will match any real controller. Some jurisdictions do not allow certain disclaimers, so some of these may not apply to you.
13. Limitation of liability
To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, revenue, data, or goodwill, arising out of or related to the Service or these Terms, even if we were told they were possible. Our total liability for all claims relating to the Service or these Terms will not exceed the greater of (a) the amounts you paid us for the Service in the 12 months before the event giving rise to the claim, or (b) US $50.
Nothing in these Terms limits liability that cannot be limited under applicable law, including liability for fraud, gross negligence, or willful misconduct, or any rights you have as a consumer that cannot be waived.
14. Indemnity
To the extent permitted by law, you will defend and indemnify us against third-party claims, losses, and reasonable costs (including attorneys' fees) arising from Your Content, your violation of these Terms, or your misuse of the Service, including any use of the Service or programs tested in it to operate real equipment.
15. Governing law and disputes
These Terms are governed by the laws of the Commonwealth of Puerto Rico and applicable United States federal law, without regard to conflict-of-law rules. Before filing a claim, please contact us so we can try to resolve the issue informally within 30 days. Any dispute that cannot be resolved informally will be heard exclusively in the courts of Puerto Rico located in San Juan or the United States District Court for the District of Puerto Rico, and you and we consent to their jurisdiction. Either party may bring an eligible individual claim in small-claims court or file a complaint with the Puerto Rico Department of Consumer Affairs (DACO), where available.
16. Changes to these terms
We may update these Terms. The version and effective date at the top of this page show when they last changed. For material changes, we will notify you by email or in the app before the change takes effect, and we will ask you to accept the updated Terms the next time you sign in. If you do not agree to a change, stop using the Service. You can still access your Account page to delete your account or sign out.
17. General terms
- These Terms and the documents they incorporate are the entire agreement between you and us about the Service.
- If any provision is found unenforceable, the rest remains in effect, and the unenforceable provision will be applied to the fullest extent permitted.
- Our failure to enforce a provision is not a waiver of our right to do so later.
- You may not assign these Terms without our consent. We may assign them in connection with a transfer of the Service, with notice to you.
- We are not liable for delays or failures caused by events beyond our reasonable control, including hurricanes, power or internet outages, and failures of third-party providers.
- These Terms are written in English. If we provide a translation, the English version controls to the extent permitted by law.
18. Acceptable use
- Do not break the law or upload unlawful, infringing, harassing, hateful, sexually exploitative, or malicious material.
- Do not upload an employer's, client's, or other third party's confidential programs, trade secrets, credentials, personal information, or documents without authorization.
- Do not bypass authentication, rate limits, bot protection, or usage limits, including by using multiple accounts.

- Do not create accounts automatically, scrape or bulk-download the Service, or use automated access except through features we expressly provide for that purpose.
- Do not share, sell, rent, or transfer accounts; resell the Service; impersonate others; or misrepresent an affiliation.
