Privacy Policy

Last updated: 8 October 2026

Who we are

TeCombo is operated by StanleyTech ("we", "us", "our"). If you have questions about this policy or your data, contact us at privacy@stanleytech.co.uk.

What we collect

• Your email address - used to sign you in and identify your account. You can sign in with a one-time link we email you, or set a password. If you set a password we store only a salted, one-way hash of it, never the password itself.
• Photos you submit for evaluation - short bursts of images captured from your camera when you record a technique. These are sent to an AI provider for analysis and are not used by us for any purpose beyond generating your coaching feedback. We choose which AI provider handles evaluations, and we may change it from time to time - the possible providers, and the countries they are based in, are listed under "Third parties we share data with" below. We do not keep the photos ourselves after your result has been returned; only the written result is saved.
• Evaluation results and any feedback you give (agree/disagree, comments) - stored against your account so you can review your history and progress.
• Payment information - handled entirely by Stripe, our payment processor. We never see or store your card details ourselves; we only receive confirmation that a payment succeeded and which plan or credit pack you purchased.
• Which link brought you here, if any - if you arrived via a link we shared somewhere specific (for example, a particular online post), we note that once, when your account is first created, so we can tell which of our own efforts are actually useful. This is not cookie-based and does not track you across other sites - it's a single label attached to your account, never shared with anyone, and never updated again after signup.

What we don't do

We don't sell your data. We don't use tracking cookies or third-party analytics/advertising scripts. The only cookie this site sets is a session cookie used solely to keep you signed in. If you use the optional body-tracking feature, your browser downloads a code library from jsDelivr and a pose-detection model from Google Cloud Storage, so those services will see your IP address when that happens. The pose tracking itself runs on your device; no camera footage is sent to them.

How your data is used

• To provide the evaluation service itself (sending your photos to our AI provider and returning feedback to you)
• To manage your account, subscription, and credit balance
• To improve the accuracy of our coaching feedback over time, using aggregated or anonymized patterns from feedback you and other users provide - never by sharing your individual photos or personal data with anyone beyond what's needed to run the service

Third parties we share data with

• AI providers - exactly one of these processes the photos you submit to generate your coaching evaluation, depending on which is in use at the time. Each has its own terms on how long it keeps submitted data and whether it may be used to improve its models; we choose providers and settings with that in mind, but you should read their policies:
  • Anthropic (United States)
  • OpenAI (United States)
  • Google - Gemini (United States)
  • xAI - Grok (United States)
  • Xiaomi - MiMo (China)
  • Moonshot AI - Kimi (China)
  • DeepSeek (China)
  Because these providers are based outside the UK and EEA, your photos may be processed in the United States or, if one of the China-based providers is in use, in China. Where required we rely on the safeguards available for international transfers.
• Stripe - processes payments. See Stripe's privacy policy. If a payment is disputed or a refund is requested, we may share relevant account and usage information with Stripe as part of resolving it.
• Resend - sends our emails to you (sign-in links, password resets and similar). See Resend's privacy policy.
• Railway - hosts the application and stores account data.
• jsDelivr and Google Cloud Storage - supply the pose-tracking library and model described above.

How long we keep your data

We keep your account, evaluation history, and feedback for as long as your account is active. If you delete your account, your account and evaluation history are deleted immediately, not on a delay - deletion happens as a direct part of the request itself, not a batch job that runs later. Sign-in, password-reset, and email-verification links are deleted automatically once used or once they expire (15 minutes). Login records are kept for 90 days for security purposes, then automatically deleted. We keep rolling backups of our database so we can recover from a fault: daily copies are kept on our host for about two weeks, and an encrypted copy is also kept off-site by us. A deleted account therefore disappears from backups as the older copies are replaced, which can take some weeks. We don't restore a deleted account's data except to recover from a fault, and if we ever do restore a backup we delete again any accounts you had already asked us to remove. Stripe, our payment processor, retains its own transaction records independently of us, for as long as it's required to for tax and accounting purposes - we don't keep a separate copy of your payment history ourselves.

Children's privacy

TeCombo is not directed at children under 13, and we don't knowingly collect personal data from anyone under that age. We don't currently verify age at signup, so if you believe a child under 13 has created an account, or been included in a photo submitted to the service, contact us at privacy@stanleytech.co.uk and we'll delete the account and associated data.

Your rights

If you're in the UK or EU, you have rights under UK GDPR / EU GDPR to access, correct, delete, or export your personal data, and to object to or restrict certain processing. Downloading a copy of your data and deleting your account are both available directly in the app, without needing to email us - your account page has "Download my data" and "Delete my account" links that handle this immediately. For anything else, contact us at privacy@stanleytech.co.uk. You also have the right to complain to the UK Information Commissioner's Office (ICO) if you believe we've mishandled your data.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
