These Terms of Service (“Terms”) govern your use of Forge (“the App”), an iOS application provided by Supiphat Kasetrsuwan, sole proprietor, operating from Thailand (“we”, “us”). By installing or using the App, you agree to these Terms. If you don’t agree, don’t use the App.
These Terms are governed by the laws of the Kingdom of Thailand and form a legally binding contract under Thailand’s Electronic Transactions Act B.E. 2544 (2001).
FORGE IS A FITNESS TRACKING TOOL, NOT A MEDICAL DEVICE OR HEALTHCARE SERVICE.
The App provides workout logging, progressive overload calculations based on your inputs, and AI-generated training suggestions. It does not provide medical advice, diagnosis, or treatment. The App is not registered as a medical device with the Thai Food and Drug Administration (อย.) or any other regulatory body, and is not intended to be one.
Before starting any new exercise program, including any program generated or modified by the App, consult a qualified healthcare professional, especially if you:
Stop exercising and seek medical attention immediately if you experience chest pain, severe shortness of breath, dizziness, fainting, or any symptom that concerns you. The App’s AI suggestions are based on the inputs you provide; they do not account for medical conditions, medications, prior injuries, or any factor not surfaced in onboarding or check-ins.
You assume all risk of injury that may result from your use of the App, except to the extent such risk is the direct result of our gross negligence or willful misconduct (which Thai law does not permit us to disclaim — see §11).
| Field | Detail |

| Country of operation | Kingdom of Thailand |

| Service category | Information service (electronic application) under the Electronic Transactions Act B.E. 2544 |
We are not a juristic person (limited company); we operate as an individual sole proprietor. Any rights or obligations under these Terms run between you and Supiphat Kasetrsuwan personally.
We grant you a limited, non-exclusive, non-transferable, revocable license to install and use the App on iOS devices you own or control, in accordance with the Apple App Store Terms of Service and these Terms.
You may not:
The App is free to install and use for core features: workout logging, progressive overload, streaks, volume and PR tracking, and template-based programs.
Prices are listed in US Dollars. Apple charges in your local currency (Thai Baht for Thai users) at Apple’s published exchange rate. The price displayed in-app at the time of purchase is authoritative.
A 14-day free trial of Pro features begins at onboarding. You will not be charged if you cancel before the trial ends. If you do not cancel, your subscription will start automatically at the end of the trial at the price displayed at signup.
Your subscription automatically renews at the end of each billing period (monthly or annual) at the then-current price unless auto-renew is turned off at least 24 hours before the end of the current period. Your Apple ID will be charged for renewal within 24 hours prior to the end of the current period. You can manage your subscription and turn off auto-renew at any time via Settings → [Your Name] → Subscriptions → Forge on your iOS device. No refund is issued for the unused portion of any billing period.
You can cancel anytime via Settings → [Your Name] → Subscriptions → Forge → Cancel Subscription on your iOS device. Cancellation takes effect at the end of the current billing period; you retain access until then.
Refunds are processed by Apple under Apple’s refund policy. We do not issue refunds directly because we never receive your payment — Apple is the merchant of record. If you believe you are entitled to a refund under Thai consumer-protection law that Apple has refused, contact us and we will assist where reasonably possible.
Switching between monthly and annual Pro is handled through StoreKit. Apple prorates the change.
The App uses third-party large language models — currently Anthropic Claude and/or OpenAI GPT — to generate program structures, weekly check-in adaptations, and in-workout coach card suggestions (“AI Output”). AI Output is generated from the inputs you provide (goals, experience, equipment, injuries, completed sets) and from general training principles encoded in the models.
You acknowledge and agree that AI Output:
AI OUTPUT IS A TOOL AND A SUPPLEMENT, NOT A REPLACEMENT FOR INDEPENDENT JUDGMENT OR PROFESSIONAL ADVICE. You are solely responsible for deciding whether to follow any AI suggestion. You agree to:
Subject to §11 (Limitation of Liability) and to the carve-outs we cannot exclude under Thai law (gross negligence, willful misconduct, bodily injury caused by our negligence, and non-derogable consumer-protection statutes), we bear no additional liability arising from your use of AI Output beyond the cap set in §11. The fact that AI Output is generated by third-party models we do not train or control is part of the bargain you accept when subscribing to Forge Pro.
If you believe a specific AI Output materially misled you, you may request human review of that suggestion by emailing supiphatk17@gmail.com. We will respond within 30 days with our assessment and, where appropriate, a corrected suggestion or a refund of the affected billing period at our discretion. This is in addition to your statutory rights under §15.
Personal data processed by the App is governed by our Privacy Policy, which is incorporated into these Terms by reference and complies with the Personal Data Protection Act B.E. 2562 (2019). Please read it before using AI features.
You agree not to use the App to:
We reserve the right to disable AI features or terminate access for accounts that violate these Terms. Severe or criminal violations may be reported to the Royal Thai Police Cyber Crime Investigation Bureau (CCIB) or other appropriate authorities.
The App, its source code, design, content, and trademarks are owned by Supiphat Kasetrsuwan or our licensors and are protected under the Copyright Act B.E. 2537 (1994) and the Trademark Act B.E. 2534 (1991). You receive no rights in the App except the limited license described in §3. AI-generated outputs are not copyrightable in most jurisdictions; you may use them for your personal training without restriction.
The App relies on services we do not control:
We are not responsible for outages, data loss, or behavior of these third-party services beyond reasonable diligence in selecting them.
THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTY OF ANY KIND, except for warranties that cannot be excluded under Thai law. We disclaim all other warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement.
We do not warrant that:
Where Thai consumer-protection law gives you statutory warranties or rights that cannot be excluded by contract, those rights apply regardless of this section.
TO THE MAXIMUM EXTENT PERMITTED BY THAI LAW, our total liability for any claim arising out of or related to the App is limited to the greater of (a) the amount you paid us via Apple in the 12 months preceding the claim, or (b) USD $100 (or the THB equivalent at the date of payment).
We are not liable for indirect, incidental, special, consequential, or punitive damages, including loss of profits, data, or training progress, even if advised of the possibility of such damages.
Carve-outs. The limitations in this §11 do not apply to:
You agree to indemnify and hold Supiphat Kasetrsuwan harmless from any third-party claim, damage, or expense (including reasonable legal fees) arising out of (a) your use of the App in violation of these Terms or applicable law, (b) injury or harm caused by your training activity, or (c) your violation of any third-party right.
This indemnity does not extend to claims arising from our gross negligence or willful misconduct, and does not override the protections you may have as a consumer under Thai law.
We may suspend or terminate your access to the App or to AI features at any time if you violate these Terms or misuse the App. You may stop using the App at any time by uninstalling it.
Provisions that by their nature should survive termination (disclaimers, limitations of liability, indemnification, dispute resolution) survive.
We may update these Terms periodically. Material changes will be communicated via the App or App Store update notes at least 7 days before they take effect, where reasonably practicable. Continued use of the App after the effective date of revised Terms constitutes acceptance.
If the change materially reduces your rights and you do not agree, your remedy is to cancel your subscription and uninstall the App before the effective date.
Nothing in these Terms limits, excludes, or modifies any right or remedy you have under:
If any term in this agreement is found to be an unfair contract term under Thai law, that term will be read down or severed to the extent necessary; the remainder of the Terms continues in force.
These Terms are governed by and construed in accordance with the laws of the Kingdom of Thailand, without regard to conflict-of-law principles.
Subject to §16.3, any dispute arising out of or in connection with these Terms shall be submitted to the exclusive jurisdiction of the competent civil court of Bangkok, Thailand.
If you are a consumer (ผู้บริโภค) within the meaning of the Consumer Case Procedure Act B.E. 2551 (2008), you may bring proceedings in the consumer court of your domicile in Thailand. This right cannot be waived by these Terms.
The parties may, by mutual written agreement, refer a dispute to arbitration under the rules of the Thai Arbitration Institute (TAI), seated in Bangkok, in the English language. Arbitration is not mandatory and does not displace your court rights under §16.3 unless you expressly agree.
Subject to mandatory law, any claim relating to these Terms must be brought within the limitation periods set out in the Thai Civil and Commercial Code (generally one or ten years depending on claim type).
These Terms are provided in English. A Thai-language version may be made available for users in Thailand on request. In the event of any inconsistency between an English version and a Thai version, the Thai version will prevail for users domiciled in Thailand, in accordance with mandatory Thai consumer-protection norms.
The provisions in this §19 apply in addition to §§1–18 above and prevail to the extent of any inconsistency for users domiciled in the listed region. Nothing here reduces rights granted under §§1–18 or under the regional law itself.
If you are a resident or domiciled in the EEA, the United Kingdom, or Switzerland, the following apply:
Mandatory consumer rights. The non-derogable rights granted by the EU Consumer Rights Directive 2011/83/EU, the Unfair Contract Terms Directive 93/13/EEC, the Digital Content Directive 2019/770/EU, the UK Consumer Rights Act 2015, and your member state’s implementing legislation apply regardless of any contrary provision in these Terms. The court in your member state of habitual residence has jurisdiction over any consumer dispute.
Governing law for consumers. Notwithstanding §16.1, where you are a consumer (a natural person acting outside your trade, business, craft, or profession), the law of your member state of habitual residence governs any matter that is the subject of a non-derogable consumer-protection rule of that state.
Forum for consumers. Notwithstanding §16.2, you may bring proceedings in the courts of your member state of habitual residence. We will only sue you in the courts of your member state of habitual residence.
Subscription cancellation. You may cancel a subscription within 14 days of purchase under Article 9 of the EU Consumer Rights Directive (the “withdrawal period”). Where the App’s paid features have begun to be supplied with your prior express consent and acknowledgement that the right of withdrawal is lost once performance has fully begun, the withdrawal right may not apply (Article 16(m) CRD). Apple’s refund flow remains the operational route.
Mandatory disclosures (UK Consumer Rights Act §49 / DCD Art 8). Digital content supplied by us must be of satisfactory quality, fit for purpose, and as described. Where the content fails these standards, you are entitled to a price reduction or refund as set out in the relevant statute.
Liability. Notwithstanding §11, our liability cannot be limited or excluded:
Unfair contract terms. Standard-form terms in these Terms that are deemed “unfair” under your member state’s transposition of Directive 93/13/EEC (or, in the UK, under the Consumer Rights Act 2015 Part 2) are not binding on you. The remainder of the Terms continues in force.
If you are a California resident, the following apply under the California Consumer Privacy Act (CCPA), as amended by the California Privacy Rights Act (CPRA) and other California consumer-protection statutes:
Consumer rights. You have the rights to know, access, delete, correct, and opt out described in the Privacy Policy §13.2.
No sale or sharing of personal information. We do not sell your personal information, and we do not share it for cross-context behavioral advertising as defined in Civil Code §1798.140(ah). No “Do Not Sell or Share My Personal Information” link is required, but we will treat any opt-out request as honored.
Shine the Light (§1798.83). We do not disclose your personal information to third parties for those parties’ direct-marketing purposes.
Subscription auto-renewal disclosure (Business & Professions Code §17602). Before your purchase, the price, billing frequency, and cancellation method are presented to you on the Apple StoreKit purchase confirmation sheet. You may cancel at any time via Settings → [Your Name] → Subscriptions → Forge on your iOS device. Apple is the merchant of record; refund requests are processed by Apple under Apple’s published refund policy.
California-specific liability. Notwithstanding §11, where applicable, our liability for personal injury caused by our negligence cannot be limited under California Civil Code §1668.
If you are a resident of any US state with a comprehensive consumer-privacy law (currently including Colorado, Connecticut, Delaware, Indiana, Iowa, Kentucky, Maryland, Minnesota, Montana, Nebraska, New Hampshire, New Jersey, Oregon, Rhode Island, Tennessee, Texas, Utah, Virginia, or another state with substantively equivalent law) you have the consumer-privacy rights granted by your state’s statute. Procedurally these rights are exercised through the same channels described for California users in §13.2 of the Privacy Policy, with the response timelines, exemptions, and appeal rights of your state’s statute applied.
State subscription auto-renewal laws. Auto-renewal of paid subscriptions is disclosed through Apple’s StoreKit purchase confirmation sheet at point of sale, in compliance with the respective state law (e.g., New York General Business Law §527-a, Illinois Automatic Contract Renewal Act 815 ILCS 601, etc.).
If you are domiciled in a Canadian province or territory other than Quebec, the Personal Information Protection and Electronic Documents Act (PIPEDA) governs our processing of your personal information. Your provincial Consumer Protection Act may grant additional rights.
Liability. Notwithstanding §11, our liability cannot be excluded:
Forum. You may bring consumer-protection proceedings in the court of your province of residence.
Quebec is excluded from Forge’s territory list for v1.0 (Charter of the French Language requirements + Law 25 are not yet supported). If you reside in Quebec, Forge is not currently offered to you and any account created in error will be deleted on request.
If you are an Australian resident, non-excludable consumer guarantees under the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010) apply, including:
Liability for these guarantees cannot be limited or excluded by these Terms. Where we provide services and the services fail these guarantees, you are entitled to remedies under Part 5-4 of the ACL.
Forum. You may bring proceedings in the court of your state or territory of residence.
Privacy. The Australian Privacy Act 1988 and the Australian Privacy Principles (APPs) apply to our processing of your personal information. The Notifiable Data Breaches scheme applies — we will notify the Office of the Australian Information Commissioner (OAIC) and affected individuals as required.
If you are a New Zealand resident, the Privacy Act 2020 governs our processing of your personal information. The Fair Trading Act 1986 and the Consumer Guarantees Act 1993 grant non-excludable consumer guarantees substantially equivalent to those in §19.5.
If you are a Singapore resident, the Personal Data Protection Act 2012 (SG-PDPA) governs our processing of your personal information. The Consumer Protection (Fair Trading) Act (CPFTA) grants non-excludable rights to a remedy for unfair practices. You may lodge complaints with the Personal Data Protection Commission Singapore (PDPC).
If you are a South African resident, the Protection of Personal Information Act, 2013 (POPIA) governs our processing of your personal information. The Consumer Protection Act, 2008 (CPA-ZA) grants non-excludable consumer rights. You may lodge complaints with the Information Regulator.
Forge is currently distributed only in the territories listed in docs/MARKETS.md §2. If you are accessing Forge from a territory not in that list, your access may be unauthorized and you accept all consequences of that unauthorized access including the application of these Terms under their default governing-law and forum clauses (§16).
These Terms are provided grounded in Thai law (PDPA, Consumer Protection Act, Civil and Commercial Code, Computer Crime Act, Electronic Transactions Act, Unfair Contract Terms Act) with region-specific addenda for the EU/EEA/UK, USA, Canada, Australia, New Zealand, Singapore, and South Africa. They are NOT legal advice. Have a Thai-qualified lawyer (and ideally counsel in any region of material exposure) review before publishing — especially the §11 liability cap, §16 forum and arbitration clauses, the §17 language clause, and the §19 regional addenda.
