Terms of Service

These Terms of Service ("Terms") govern your use of TilePro Calculator (tileprocalculator.com), a free, browser-based tile layout calculator for contractors, installers, and DIY users. The site is operated by an independent developer — there is no corporate entity behind this site.

We aim for plain language, not legalese. If anything here is unclear, reach out via the About page.

• The calculator gives estimates only — always verify your own measurements and consult a pro before you buy materials
• The service is free and provided "as is," with no warranties and limited liability
• You must be at least 13 to use the site; under 18s need a parent or guardian
• Don't abuse the service — no spam, scraping, or illegal use
• You own what you save or submit; you grant us a license to host and display it so the service can work

By accessing or using the site, you agree to be bound by these Terms and by our Privacy Policy. If you don't agree, please don't use the site.

You must be at least 13 years old to use TilePro Calculator. If you are under 18, you may only use the service with the involvement and consent of a parent or legal guardian, who accepts these Terms on your behalf. By using the site, you represent that you meet these requirements.

TilePro Calculator provides tile-layout tools including a basic length × width calculator, an advanced wall-by-wall room builder, a pattern library (herringbone, brick, diagonal, and others), cut optimization, PDF export, URL-based layout sharing, educational guides, and a changelog. Most calculations run directly in your browser.

The service is currently offered free of charge. We may add, change, suspend, or discontinue any feature at any time, with or without notice. We may also impose limits on certain features or restrict access to parts of the site.

You can use most of the site without an account. An optional Google sign-in (via Neon Auth) unlocks the dashboard at /dashboard where you can save, load, rename, and delete layouts.

• You are responsible for maintaining the security of the Google account you sign in with
• One account per person; no sharing of accounts
• You are responsible for all activity that happens under your account
• You can delete your account at any time from your dashboard settings, which triggers removal of your saved layouts and associated account data
• We may suspend or terminate accounts that violate these Terms

When using TilePro Calculator, you agree NOT to:

• Use the service for any illegal purpose
• Send spam or attempt to phish other users or the operator
• Attempt to overload, disrupt, or impair the service (e.g., denial-of-service attempts)
• Scrape, crawl, or automate access beyond normal browser use, or bypass robots.txt, rate limits, or other access controls
• Submit abusive, harassing, hateful, defamatory, sexually explicit, or otherwise objectionable content in layout names, custom pattern names, contractor feedback, or anywhere else you can enter text
• Reverse engineer, decompile, or attempt to extract source code beyond what is allowed by applicable law
• Circumvent or attempt to circumvent rate limits, abuse controls, or access restrictions
• Use the service to build or train a competing product, including via automated data collection
• Impersonate another person or misrepresent your affiliation with any person or entity

"User Content" means anything you submit through the site, including saved layout names (up to 200 characters), layout data, custom tile patterns, and contractor-feedback form submissions.

You keep ownership of your User Content. By submitting it, you grant the operator a non-exclusive, worldwide, royalty-free license to host, store, reproduce, display, and process that content solely as needed to operate and provide the service to you (for example, saving a layout so you can reload it later, or reviewing your feedback).

You represent and warrant that you have all the rights needed to submit your User Content and that it does not infringe any third-party rights or violate any law.

We may remove or refuse User Content that we believe violates these Terms or is otherwise objectionable, at our discretion.

TilePro Calculator provides estimates only. Tile quantities, cut counts, waste estimates, material lists, and layout diagrams are approximations generated from the measurements you enter.

Before you buy materials or start a project, you must:

• Independently verify all measurements
• Consult a licensed professional (contractor, installer, designer, or engineer as applicable) for any non-trivial project
• Account for your specific project conditions — wall irregularities, slope, substrate, grout width, pattern alignment, focal points, code requirements, and so on
• Factor in an appropriate waste / overage allowance beyond what the tool may suggest

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF HARMFUL COMPONENTS, OR THAT CALCULATIONS WILL BE ACCURATE OR SUITABLE FOR YOUR PROJECT.

To the maximum extent permitted by applicable law, the operator will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, materials, or project costs, arising out of or related to your use of the service — even if we have been advised of the possibility of such damages.

The operator's total aggregate liability for any claim arising out of or relating to the service or these Terms will not exceed the greater of (a) one hundred U.S. dollars ($100 USD) or (b) the total amount you paid to use the service in the twelve (12) months before the event giving rise to the claim — which, for a free tool, is $0.

Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above may not apply to you. Nothing in these Terms limits liability for gross negligence, fraud, willful misconduct, or bodily injury where such limits are prohibited by law.

You agree to defend, indemnify, and hold harmless the operator from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorney's fees) arising out of or related to (a) your use of the service, (b) your User Content, (c) your violation of these Terms, or (d) your violation of any law or the rights of a third party.

The site — including its source code, guides, design, visual assets, branding, and the TilePro name and logo — is owned by the operator and protected by copyright, trademark, and other laws. Content provided by third parties (such as typefaces) remains the property of those third parties.

You are granted a limited, personal, non-transferable, non-exclusive license to access and use the site for your own personal or professional tile-planning purposes. You may not copy, redistribute, republish, or commercially exploit the site's content without written permission. You may not use the TilePro name or logo to imply endorsement or affiliation.

We respect intellectual-property rights. If you believe content on the site infringes your copyright, please send a written notice to admin@zharv.me with the following information:

• Identification of the copyrighted work you claim has been infringed
• Identification of the material on the site that you claim is infringing, including a URL or other specific location
• Your name, mailing address, phone number, and email
• A statement that you have a good-faith belief the use of the material is not authorized by the copyright owner, its agent, or the law
• A statement, under penalty of perjury, that the information in your notice is accurate and that you are the copyright owner or authorized to act on the owner's behalf
• Your physical or electronic signature

We will respond to valid notices in accordance with the Digital Millennium Copyright Act. Repeat infringers' accounts may be terminated.

Our Privacy Policy explains how we collect, use, and share information. By using the service you also agree to that policy.

The site integrates third-party services including Google (OAuth via Neon Auth, Google Fonts, Google Analytics), Microsoft Clarity, Vercel, Neon, and Resend. When you interact with those services, their own terms and privacy policies apply in addition to ours. See the Privacy Policy for details on what each service does.

You can stop using the site at any time. If you have an account, you can delete it from your dashboard settings, which removes your saved layouts and associated account data.

We may suspend or terminate your access to the service — or any part of it — at any time, with or without notice, for any reason, including if we believe you have violated these Terms. For serious or repeated violations we may act immediately and without notice.

Sections that by their nature should survive termination — including User Content license (for content already distributed), warranty disclaimer, limitation of liability, indemnification, intellectual property, governing law, and dispute resolution — will survive.

We may update these Terms from time to time. When we do, we'll post the revised version on this page and update the "Last updated" date at the top. Material changes will be signaled by the updated date and, where practical, a more visible notice. Your continued use of the service after changes take effect means you accept the revised Terms.

These Terms are governed by the laws of the State of Illinois, United States, without regard to its conflict-of-laws rules. Except for small-claims matters (which either party may bring in an appropriate small-claims court), any action arising out of or relating to these Terms or the service must be brought in the state or federal courts located in that state, and you consent to personal jurisdiction and venue there.

Before filing a formal claim, please try to resolve the dispute informally by contacting the operator via the About page. We'll make a good-faith effort to resolve any issue quickly.

If we can't reach a resolution, disputes will be handled in the courts identified in the Governing Law section above. These Terms do not require binding arbitration and do not waive your right to participate in a class action — for a free indie tool, neither is appropriate.

Severability. If any provision of these Terms is found unenforceable, the rest remain in full force and effect, and the unenforceable provision will be modified to the minimum extent necessary to make it enforceable while preserving its intent.

Entire agreement. These Terms, together with the Privacy Policy, are the entire agreement between you and the operator regarding your use of the service, and supersede any prior agreements on the subject.

No waiver. Our failure to enforce any provision is not a waiver of our right to enforce it later. You may not assign these Terms without our written consent; we may assign them freely.
