Terms of Service

1. Eligibility and accounts

The Service is intended for business use by construction professionals. You must be at least 18 years old and have the authority to bind the business on whose behalf you use the Service.

You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. Notify us immediately of any unauthorized use. We are not liable for losses caused by unauthorized use of your account.

You agree to provide accurate registration information and keep it current. We may refuse, suspend or reclaim accounts at our reasonable discretion (e.g., impersonation, abuse, fraud).

2. The Service

Buldos is a software tool that assists with construction estimating: quantity takeoff based on data you enter, material and labour cost calculations, supplier price imports, tax calculations and quote document generation.

We may add, modify or discontinue features at any time. Where a change materially reduces core functionality you have paid for, we will provide reasonable advance notice.

3. ESTIMATES ARE AIDS ONLY — NO GUARANTEE OF ACCURACY

THIS SECTION IS THE BASIS OF THE BARGAIN. THE SERVICE PRODUCES CALCULATIONS BASED SOLELY ON DATA, DIMENSIONS, PARAMETERS AND PRICES ENTERED OR IMPORTED BY YOU. ALL OUTPUTS — INCLUDING QUANTITIES, WASTE FACTORS, LABOUR HOURS, PRICES, TAXES AND TOTALS — ARE ESTIMATES PROVIDED FOR INFORMATIONAL PURPOSES ONLY.

You must independently verify all quantities, prices, dimensions, code requirements and tax treatments before relying on any output, including before submitting a bid, signing a contract, ordering materials, or invoicing a client.

The Service is not a substitute for, and does not provide, architectural, engineering, code-compliance, legal, tax or accounting advice. Items flagged for engineering review (e.g., long-span headers) REQUIRE assessment by a licensed professional. Default formulas, waste factors and labour norms are industry approximations that may not match your project, region, or code edition.

Readiness labels such as "Reviewed", "Supported" or "Procurement candidate" describe the completeness of evidence recorded in the Service. They are not a warranty, certification, professional seal, code approval or authorization to construct. A regional data pack marked Reference or Reviewed is not a fully supported jurisdiction.

Draft exports, estimates with unresolved gates, and outputs for unsupported jurisdictions must not be used for procurement or construction. Removing, obscuring or misrepresenting a Service-generated readiness label, assumption, exclusion or warning is prohibited.

For traceability and dispute resolution, the Service may retain immutable estimate snapshots, acceptance records and audit events identifying material changes to quantities, scope, prices and overrides, subject to the Privacy Policy and applicable retention law.

YOU ARE SOLELY RESPONSIBLE FOR YOUR BIDS, CONTRACTS, PURCHASES, PRICING DECISIONS AND ANY RESULTING PROFIT OR LOSS. WE SHALL HAVE NO LIABILITY WHATSOEVER FOR UNDERBIDS, OVERBIDS, MATERIAL SHORTAGES OR OVERAGES, LOST TENDERS, PROJECT DELAYS, OR ANY OTHER CONSEQUENCE OF RELIANCE ON SERVICE OUTPUTS.

4. Credits, fees and payment

Certain features consume prepaid export credits sold in packs. Credits: (a) are prepaid and consumed per the pricing rules shown in the app; (b) have no cash value; (c) are non-transferable between accounts; (d) do not expire; and (e) are refundable only as set out in the Refund Policy.

Payments are processed by Stripe. By purchasing you also agree to Stripe's terms. Prices are shown at checkout in the applicable currency (Canadian dollars unless stated otherwise) and are exclusive of applicable taxes unless stated otherwise. We may change pack pricing prospectively at any time; changes do not affect credits already purchased.

A negative credit balance (e.g., following a refund of a partially used pack) suspends paid features until the balance is restored.

We may suspend the account and paid features while any chargeback or payment dispute is pending.

5. Free tier and fair use

The free tier includes limited functionality (currently one watermarked export per calendar month) and may be changed or withdrawn at any time. Automated, scripted or multi-account use intended to circumvent limits is prohibited and may result in termination without refund.

6. Your content and data

You retain ownership of the data you enter or upload (projects, client details, price lists, plans) ("Customer Content"). You grant us a worldwide, non-exclusive licence to host, process, display and transmit Customer Content solely to provide and improve the Service.

You represent and warrant that you have all rights necessary to upload Customer Content — including supplier price lists and any personal information of your clients — and that our processing of it on your instructions will not violate any law or third-party right.

We may generate and use aggregated, de-identified statistics (e.g., anonymous price benchmarks) that do not identify you or your clients; such data is ours.

We may remove Customer Content that we reasonably believe is unlawful or infringing.

7. Acceptable use

You must not: (a) reverse engineer, decompile or copy the Service or its calculation formulas, assemblies or material dictionaries except as permitted by law; (b) resell, sublicense, or provide the Service to third parties as a bureau service; (c) scrape or bulk-export system data; (d) probe or test the security of the Service without written permission; (e) upload malware or unlawful content; (f) use the Service to violate any law.

We may suspend or terminate accounts that breach this section, with forfeiture of remaining credits.

8. Intellectual property

The Service — including software, design, calculation engines, assembly templates, the materials dictionary and documentation — is owned by us and protected by intellectual property laws. These Terms grant you a limited, non-exclusive, non-transferable, revocable licence to use the Service for your internal business purposes. No rights are granted except as expressly stated.

Feedback you provide may be used by us without restriction or compensation.

9. Third-party services

The Service relies on third-party providers, including Stripe (payments), Vercel and Render (hosting), Supabase (database hosting) and, where AI plan analysis is enabled, an AI model provider. We are not responsible for the acts, omissions or outages of third-party providers. Their terms and privacy policies apply to their processing.

10. Availability and support

The Service is provided on an "AS IS" and "AS AVAILABLE" basis without any service-level commitment. We do not warrant uninterrupted or error-free operation. We may perform maintenance with or without notice. Support is provided on a commercially reasonable, best-effort basis via support@buldos.com.

You are responsible for exporting and backing up documents you need. We may delete data of accounts inactive for more than 12 months on the free tier after notice to the account e-mail.

11. Disclaimer of warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR TRADE USAGE. NO ADVICE OR INFORMATION OBTAINED FROM US OR THE SERVICE CREATES ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (A) IN NO EVENT SHALL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST BIDS OR TENDERS, LOSS OF DATA, BUSINESS INTERRUPTION OR REPUTATIONAL HARM, EVEN IF ADVISED OF THE POSSIBILITY; AND (B) OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE SHALL NOT EXCEED THE GREATER OF (i) THE AMOUNTS YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM AND (ii) ONE HUNDRED CANADIAN DOLLARS (CAD $100).

These limitations apply regardless of the theory of liability (contract, tort, negligence, strict liability or otherwise) and even if a remedy fails of its essential purpose. Some jurisdictions do not allow certain exclusions; in that case the exclusions apply to the fullest extent permitted, and nothing in these Terms excludes liability that cannot be excluded by law (including under applicable consumer protection legislation).

13. Indemnification

You will defend, indemnify and hold harmless us and our officers, directors, employees and agents from and against any claims, damages, liabilities, costs and expenses (including reasonable legal fees) arising out of or related to: (a) Customer Content; (b) your use of Service outputs, including any bid, contract, invoice or purchase based on them; (c) your breach of these Terms or of any law; or (d) your violation of any third-party right, including your clients' privacy rights.

14. Suspension and termination

You may stop using the Service and request account deletion at any time. We may suspend or terminate your access immediately for breach of these Terms, suspected fraud or abuse, non-payment, chargebacks, or where required by law.

Upon termination for breach, remaining credits are forfeited without refund. Upon termination without cause by us, we will refund the unused credit balance pro-rata. Sections 3, 6 (licence for retention period), 8, and 11–17 survive termination.

After account closure we retain data only as described in the Privacy Policy, then delete it.

15. Changes to these Terms

We may update these Terms from time to time. Material changes will be announced by e-mail or in-app at least 14 days before they take effect. Continued use of the Service after the effective date constitutes acceptance. If you do not agree, stop using the Service before the effective date and contact us regarding unused credits.

16. Governing law and disputes

These Terms are governed by the laws of the Province of Alberta and the federal laws of Canada applicable therein, without regard to conflict-of-laws rules. The courts located in Calgary, Alberta have exclusive jurisdiction, and the parties attorn to their jurisdiction. To the extent permitted by law, each party waives any right to participate in a class or representative action; claims must be brought individually.

Nothing in this section deprives you of the protection of mandatory consumer-protection provisions of the jurisdiction in which you reside, where those apply to you notwithstanding the choice of law.

16A. United States users

The Service is offered from Canada. If you access it from the United States, you are responsible for compliance with your local laws, and the following applies in addition to these Terms.

Construction codes: default assemblies, formulas and constants reference Canadian practice (e.g., NBC-informed defaults); US building codes (IRC/IBC and state or local amendments) may differ. Taxes: US quotes apply the STATE BASE sales tax rate only — county, city and special-district surtaxes are NOT included, and contractor-specific tax treatment of materials and labour varies by state. Verify code requirements and the correct tax treatment for your jurisdiction before using any output.

DISPUTES (US): to the extent permitted by law, any dispute that cannot be brought in the courts of Calgary, Alberta shall be resolved by binding individual arbitration administered under the rules of a recognized arbitration provider in your state, and BOTH PARTIES WAIVE THE RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION. You may opt out of this arbitration provision within 30 days of account creation by e-mailing support@buldos.com. Small-claims-court claims are not subject to arbitration.

Nothing in these Terms limits rights you hold under non-waivable US federal or state law, including state consumer-protection statutes.

17. General

These Terms, together with the Privacy Policy and Refund Policy, are the entire agreement between you and us regarding the Service and supersede all prior agreements. If any provision is held unenforceable, it will be modified to the minimum extent necessary and the rest remains in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition or sale of assets. We are not liable for delays or failures caused by events beyond our reasonable control (force majeure).
