TET Accessibility API. Last updated 25 July 2026.
This policy explains what the TET Accessibility API (the "Service") collects when you use the WordPress plugin TET Accessibility for WooCommerce (the "Plugin"). The Service is operated by TET, based in Japan.
The Plugin works without an account. Scanning your site, reading the issue list, dismissing findings and exporting the CSV all happen on your own server, and nothing is sent to us. Data only reaches us in three situations, all of which you trigger yourself: requesting a key, pressing "Suggest a fix", and opening the settings screen while a key is saved.
| Data | Why | Kept for |
|---|---|---|
| Email address | To send you the key and contact you about the account | Until you ask us to delete it |
| Site URL | To support you and to detect abuse of the free tier | Until you ask us to delete it |
| A one-way hash of your IP address | To rate-limit free key issuance. We do not store the address itself and cannot recover it from the hash | 30 days |
| Data | Why | Kept for |
|---|---|---|
| The rule that fired and its WCAG reference | To generate the suggestion | Not stored after the response |
| The description of the finding | To generate the suggestion | Not stored after the response |
| The HTML snippet already shown to you in your admin | To generate the suggestion. Truncated to 1,200 characters before it is sent onward | Not stored after the response |
| The page type (shop, product, cart, checkout or account) | To generate the suggestion | 12 months, as a usage record |
| Your site locale | To answer in your language | Not stored after the response |
| Your site address | To apply the site limit on your plan. Normalised, so http/https and a www prefix are not counted as separate sites | Until you or we release the activation, or 60 days without use |
| Your API key | Authentication and quota accounting | Stored only as a hash; see below |
| Token counts and a timestamp | Billing and capacity planning | 12 months |
We keep a usage record of which rule a suggestion was requested for and when. We do not retain the markup or the finding text after your response has been returned.
The Plugin's settings screen asks the Service how many suggestions remain on your plan. Only your API key is sent, and the answer is cached for one hour. Removing the key from the Plugin stops this.
If you buy a paid plan, our payment provider tells us your email address and which plan you bought, so we can move your key onto it. We never see your card details; the payment provider handles those and is the merchant of record.
The Plugin does not send, and the Service is not built to accept: customer records, orders, payment information, user accounts, passwords, post or page content, or full copies of any page. The scan itself runs on your own server and its results stay in your own database.
We store a SHA-256 hash of your key, never the key itself. If you lose it we cannot recover it, only issue a replacement.
| Processor | Role | Location |
|---|---|---|
| Anthropic PBC | Generates the suggestion text from the finding and markup you submit | United States |
| Our hosting provider | Runs the Service and its database | See our website for the current provider |
| Our email provider | Delivers API keys and account email | See our website for the current provider |
Anthropic processes submitted content to return a response. Per Anthropic's commercial terms, inputs and outputs from API customers are not used to train their models. We do not sell your data, and we do not use it for advertising.
We are based in Japan and our AI processor is in the United States, so data you submit is transferred outside the EEA and the UK. Where those transfers concern personal data, we rely on the European Commission's adequacy decision for Japan and on Standard Contractual Clauses with our processors.
You may ask us to give you a copy of your data, correct it, delete it, restrict or object to its processing, or export it. Email support@tetphilosopher.com and we will respond within 30 days. Deleting your account removes your email address, site URL, key hash and usage records.
If you are in the EEA or the UK and you are unhappy with our response, you may complain to your national data protection authority. In Japan, the Personal Information Protection Commission handles such complaints.
The Service is an API and sets no cookies. This documentation site uses no analytics and no tracking.
The Service is a developer tool and is not directed at anyone under 16. We do not knowingly collect data from children.
All traffic is encrypted in transit with TLS. API keys are stored only as hashes. Access to production data is limited to the operator of the Service. No system is perfectly secure; if a breach affects your data we will notify you and, where required, the relevant regulator.
If we change this policy materially we will update the date above and notify account holders by email before the change takes effect.
