Fireworks are real. People get hurt every year. This software is a planning aid — it helps you design a rack — not an engineering certification. The mortar tubes it generates fit only standard 1.9″ consumer shells (a "Reference Shell"); larger shells physically won't fit. Follow your local law, keep spectators back at least 100 feet per inch of shell diameter (so ≥ 190 ft for a Reference Shell), use an appropriate ignition method per local law and the shell manufacturer's instructions, and read this whole document before you download anything you plan to build from.

Forge and Boom is a planning aid for adult U.S. hobbyists who build mortar racks for consumer-grade aerial mortar shells with an outer diameter of 1.9 inches or smaller (the "Reference Shell"). The Service produces 3D-printable mortar tube and base files, a do-it-yourself construction plan, ballistic visualizations, and a fuse-sequence preview.
The Service is not engineering certification, professional consulting, or a substitute for trained pyrotechnic judgment. It generates designs; you build them. The mortar tubes produced by the Service are sized to accept the Reference Shell only. Loading any shell with an outer diameter greater than the Reference Shell into those tubes is intended to be physically prevented by the printed tube geometry and is, in any event, outside the scope of every safety figure provided by the Service.
You may use the Service only if you are at least 18 years old, located in the United States, and lawfully entitled to design, build, possess, and discharge consumer-grade aerial fireworks where you intend to act.
You accept this Agreement by clicking a checkbox or button labeled "I agree" (or substantially equivalent) when you create an account, claim a Founders Club pass, purchase a Season Pass, or download any build artifact. Each acceptance is logged with your account identifier, the version of this Agreement in effect, and a timestamp. Per-export safety acknowledgments substantially in the form of Schedule A are similarly logged. Browsing the marketing site without accepting this Agreement does not bind you to it; using the design tool, downloading any file, or purchasing any pass does.
You are solely responsible for:
(a) Legal compliance. Confirming that designing, building, possessing, transporting, loading, igniting, and displaying consumer-grade fireworks of the size and quantity in your rack is lawful in every federal, state, county, and municipal jurisdiction in which you will act, and obtaining any required permits. The Service does not check your local law.
(b) Safe construction. Inspecting every component of any rack you build; verifying that lumber, hardware, fasteners, plates, glues, and 3D-printed parts you supply meet the loads imposed during loading, transport, and ignition; rejecting any output of the Service that you do not understand.
(c) Safe operation. Maintaining spectator distances of at least 100 feet per inch of shell diameter (the outer diameter of the shell itself, not the launching tube — for the Reference Shell, a minimum of 190 feet); confirming weather; using an appropriate ignition method per local law and the shell manufacturer's instructions; wearing eye and ear protection; preparing predetermined wait times for misfires; keeping water, sand, and a charged fire extinguisher within arm's reach throughout; and following every safety instruction issued by the manufacturer of every shell loaded into the rack.
(d) Third-party safety. Any injury, death, property damage, emotional distress, environmental damage, or other harm caused by the construction, transport, loading, ignition, display, malfunction, or aftermath of any rack designed using the Service.
Loading any shell larger than the Reference Shell, modifying the printed tubes, or substituting non-Service-printed tubes into a rack frame designed by the Service voids every setback figure, ballistic estimate, and safety calculation provided by the Service.
Consumer fireworks are inherently dangerous. Mortar racks concentrate that danger. Defects in design, materials, construction, shell quality, fuse variance, operator error, or weather can cause severe burns, hearing loss, blindness, dismemberment, death, fire, and property damage. You knowingly and voluntarily assume all such risks, on behalf of yourself and any person whose participation or presence is foreseeable. To the maximum extent permitted by Tennessee law, you waive any claim or cause of action against the Company arising from your voluntary assumption of these risks.
Subject to your full and continuing compliance with this Agreement (and, where applicable, payment of the fees in Section 6), the Company grants you a personal, non-exclusive, non-transferable, non-sublicensable, revocable license to use the Service and to download, print, build, and personally display the build artifacts it produces. Commercial use, resale, and redistribution of build artifacts are prohibited without our prior written consent.
You retain ownership of the rack designs and configurations you create. You grant the Company a worldwide, royalty-free license to use aggregated, anonymized information derived from your designs solely to improve the Service. We do not claim ownership of, and will not publicly publish, your individual designs.
All Service software, content, branding, and trademarks remain the Company's property. You may not reverse-engineer, decompile, or circumvent technical limitations of the Service except to the limited extent applicable law permits.
Founders Club. While open, the Founders Club grants lifetime-of-the-Service paid-tier access at no monetary cost in exchange for the registration and feedback handshake described in the claim flow.
Season Pass. Once Founders Club closes, Season Pass — $29 purchases are designated Annual and grant paid-tier access for four (4) months from the date of purchase, after which the account reverts to free-tier limits unless renewed. The first one hundred (100) Season Pass purchases (by Stripe payment timestamp) are designated Lifetime and grant paid-tier access for the operational lifetime of the Service.
Refunds. You may request a full refund within thirty (30) days of purchase by emailing chase@forgeandboom.com from the purchasing account. No reason required. After 30 days, all sales are final. The refund applies to the Season Pass fee itself, not to any material costs you have incurred.
Off-season. When a paid pass expires, designs you have created remain visible and editable; paid-tier exports require a renewed pass.
The Company may retire any tier or adjust pricing for future purchases at any time without notice; existing pass durations and prices are not affected.
THE SERVICE AND ALL BUILD ARTIFACTS ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, COMPLETENESS, OR ENGINEERING SUITABILITY. The Company does not warrant that the Service is error-free, uninterrupted, or that any build artifact will perform as you expect.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:
(a) IN NO EVENT WILL THE COMPANY, ITS OFFICERS, MEMBERS, EMPLOYEES, CONTRACTORS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR USE — INCLUDING PERSONAL INJURY, DEATH, OR PROPERTY DAMAGE CAUSED BY ANY RACK BUILT WITH THE SERVICE — WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY, AND WHETHER OR NOT THE COMPANY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
(b) THE COMPANY'S TOTAL CUMULATIVE LIABILITY UNDER THIS AGREEMENT WILL NOT EXCEED THE GREATER OF (i) THE AMOUNT YOU PAID THE COMPANY IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE LIABILITY, OR (ii) ONE HUNDRED U.S. DOLLARS ($100).
(c) Nothing in this Section limits or excludes any right or remedy that cannot be limited or excluded under the Tennessee Products Liability Act, Tenn. Code Ann. §§ 29-28-101 et seq., the Tennessee Consumer Protection Act, Tenn. Code Ann. §§ 47-18-101 et seq., or any other applicable law that cannot be waived by agreement. If any portion of this Section is held unenforceable as to a particular claim, the remainder remains in full force as to all other claims.
(d) You acknowledge that the limitations in this Section are fundamental elements of the bargain between you and the Company, and that the Company would not provide the Service without them.
You will defend, indemnify, and hold harmless the Company and its officers, members, employees, contractors, and affiliates from and against any third-party claim arising out of (a) your use of the Service, (b) your breach of this Agreement, (c) the construction, transport, loading, ignition, display, malfunction, or aftermath of any rack designed using the Service, or (d) any representation you made in any Schedule A acknowledgment. You knowingly and voluntarily accept this indemnification obligation after the opportunity to review this Agreement in full. This Section does not require you to indemnify the Company for harm caused by the Company's own gross negligence or willful misconduct, and applies only to the extent permitted by applicable law.
This Agreement is governed by the laws of the State of Tennessee, without regard to its conflict-of-laws principles. Any dispute arising out of or relating to this Agreement or the Service will be resolved by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, seated in Knox County, Tennessee, with judgment on the award entered in any court of competent jurisdiction.
Carve-outs. The arbitration requirement does not apply to: (a) claims arising under the Tennessee Products Liability Act; (b) claims arising under the Tennessee Consumer Protection Act to the extent such claims are non-waivable; (c) small-claims-court actions within that court's jurisdictional limits; or (d) actions for injunctive relief to protect intellectual property. Class actions and class arbitration are waived to the maximum extent permitted by law.
(a) Changes. We may amend this Agreement by posting a new version and updating the Effective Date. We will use reasonable efforts to notify you of material changes. For material changes, we will obtain your renewed clickwrap acceptance (per Section 2) before applying the changed terms to your account. The version in effect at the time you accepted (logged per Section 2) governs disputes about events that occurred under that version.
(b) Termination. We may suspend or terminate your access at any time for any breach of this Agreement, for safety reasons, or for discontinuation of the Service. Sections 3 (with respect to any rack you have already built or are in the course of building), 4, 5, 6 (with respect to refund obligations within the refund window), 7, 8, 9, 10, and 11, together with Schedule A acknowledgments already logged, survive termination.
(c) Notices. We send notices to the email address associated with your account; they are effective when sent. You send notices to chase@forgeandboom.com.
(d) Force majeure. Neither party is liable for delays or failures caused by events beyond reasonable control.
(e) Severability and entire agreement. If any provision is held unenforceable, the remainder remains in force. This Agreement, together with the Privacy Policy and any posted Schedule, is the entire agreement between you and the Company regarding the Service and supersedes any prior agreement on the same subject.
(f) No assignment by you. You may not assign this Agreement; we may assign it to a successor in a merger, acquisition, or sale of assets.
(g) Independent parties. Nothing in this Agreement creates an agency, partnership, joint venture, or employment relationship.
