Terms of service

The agreement

Written to be read. The clauses that matter are the fourth and the ninth: Taggart does not determine legal compliance, and it will not change how your documents look.

1. Who this is between

These terms are between you — the person or organisation using the service — and Codama Advanced Engineering, Inc., a Delaware C-Corporation with its registered office at 8 The Green, Ste A, Dover, DE 19901, USA, which operates Taggart. “We” and “us” mean Codama; “you” means the subscriber.

2. What the service is

Taggart examines PDF files against the Matterhorn Protocol, PDF/UA-1 (ISO 14289-1), WCAG 2.1 and the Israeli standard IS 5568, reports what it finds, applies repairs you approve, and produces a report recording what was done and who decided it.

Validation is free and unlimited and requires no account. Remediation, the reading-order editor and the report require a paid plan.

The free tier is subject to a fair-use allowance on automated requests, stated in the response when it is reached. It exists to keep the service available, not to meter you.

3. What the service is not

Taggart does not determine legal compliance, and nothing it produces is a legal determination. This is the most important clause here, so it is stated without qualification.

Of the Matterhorn Protocol's 136 failure conditions, roughly 87 can be decided by software and 47 require human judgement. No tool can decide the 47, including this one. A clean result from Taggart means the conditions it can test did not fail — it does not mean a document is accessible, and it does not mean any obligation has been met.

Whether a document satisfies the ADA, Section 508, EN 301 549, the European Accessibility Act, IS 5568 or any other instrument is a determination made by a qualified person with the document in front of them. In Israel that is a licensed מורשה נגישות. You remain responsible for your own obligations.

We do not provide legal advice. Nothing on this site or in any report is legal advice.

4. Your documents remain yours

You keep all rights in the files you upload. You grant us only the licence needed to run the service on them: to store, process, render and return them, for as long as the job and its retention window require.

We do not use your documents to train models. We do not read them except as needed to operate and support the service. Retention and deletion are described in the privacy policy, which forms part of these terms.

You confirm you have the right to upload what you upload, and that doing so does not breach anyone else's rights or any confidentiality obligation you are under.

5. Acceptable use

You agree not to:

• resell or white-label the service without a written agreement;
• present Taggart's output as a compliance certification, an audit, or a legal determination — see clause 3;
• circumvent the fair-use allowance, or run automated traffic designed to degrade the service for others;
• upload material you have no right to process;
• attempt to extract the rule set or engine for a competing product.

The published rule identifiers and their mappings to PDF/UA and WCAG are quoted from public standards and are not ours to restrict. The implementation is.

6. Subscriptions and billing

Plans are billed in advance, monthly or annually, through Stripe. Card details are handled by Stripe and never reach us. Prices are shown exclusive of tax; any VAT or sales tax applicable to you is added at checkout.

Subscriptions renew automatically at the end of each period, at the then-current price for your plan, until cancelled. We will give at least 30 days' notice by email before any price increase affecting your renewal.

You can cancel at any time from the customer portal, without contacting us. Cancellation takes effect at the end of the period you have already paid for — your access continues until then.

7. Refunds

If the service does not do what this site says it does, tell us within 30 days of the charge and we will refund it in full. You do not have to argue the point; a description of what you expected and what happened is enough.

Beyond that window we refund pro rata where we have failed materially — an extended outage, for instance. We do not refund for non-use.

Statutory rights, including any right of withdrawal you have as a consumer in the EU, the UK or Israel, are unaffected by this clause and override it where they conflict.

8. Availability

We aim for the service to be available, and we do not offer a contractual uptime guarantee on these plans. We will not deliberately take it down without notice except where a security issue requires it.

If we discontinue the service, we will give at least 90 days' notice, refund the unused portion of any prepaid period, and keep export of your reports available throughout.

9. The appearance guarantee

Remediation edits the PDF object model and not the content streams that paint the page. Every remediated file is re-rendered against the original and compared page by page at structural similarity of at least 0.999 before it is returned; a result that fails that comparison is discarded rather than given to you.

This is a term of this agreement, not a marketing claim. If a file we return renders differently from the one you uploaded, that is a breach, and clause 7 applies without the 30-day limit.

10. Warranties

We warrant that we will provide the service with reasonable skill and care, and that it will materially perform as described on this site.

Beyond that, and beyond clause 9, the service is provided as it is. We do not warrant that it will find every defect in a document — clause 3 explains why no tool can — nor that it will be uninterrupted or error free.

11. Limitation of liability

Neither party excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded.

Subject to that, our total liability arising out of this agreement is limited to the amount you paid us in the twelve months before the claim.

We are not liable for indirect or consequential loss, for loss of profit or goodwill, or — stated explicitly because it is the case that matters here — for any penalty, settlement, claim or cost arising from a determination that a document was not accessible or not compliant. Clause 3 sets out why that determination was never ours to make.

12. Ending the agreement

You may cancel at any time. We may suspend or terminate an account that breaches clause 5, or that has an unpaid invoice more than 14 days overdue, after telling you and giving you a reasonable chance to fix it.

When an account ends, documents and reports remain available for 30 days so you can export them, then are deleted.

13. Changes to these terms

We may change these terms. Material changes take effect at your next renewal and we will email you at least 30 days beforehand. If you do not accept them, cancel before that renewal and we will refund any unused prepaid period. Every version is recorded in the changelog.

14. Law and disputes

Tell us first: most disputes are a misunderstanding and we would rather fix one than argue it. Write to hello@codama.dev and we will reply.

If that does not resolve it, these terms are governed by the laws of the State of Delaware, without regard to its conflict-of-law rules, and the United Nations Convention on Contracts for the International Sale of Goods does not apply. Proceedings go to the state or federal courts located there, and we each agree to that.

Unless you are a consumer. If you are using Taggart for purposes outside your trade or profession, nothing above takes away the protections your own country's law gives you, and you may bring proceedings in the courts where you live. In Israel, in the European Union and in the United Kingdom those protections cannot be contracted away, and we are not trying to.

There is no arbitration clause here and no waiver of class actions. Both are ordinary in software terms and both work by making disputes expensive to bring, which is a strange thing to ask of a product sold on the argument that it refuses to over-claim.
