Privacy Policy

Last updated: 05.11.2026

This policy explains which personal data TangrAI processes, why, on what legal basis, who we share it with and what rights you have.

1. Data controller

TangrAI is provided by Veneta Dimitrova Kirilova, a natural person, address Lomska 94 Str., Kozloduy, Bulgaria ("we").

For any question about personal data: hello@tangrai.com, phone +359 878904586

2. Data we process

  • Account data: email, name, password (stored only as a bcrypt hash), preferred language, sign-up date, plan, number of generations used and whether your email is verified.
  • Google sign-in: email, name and profile picture URL, received from Google through Emergent's sign-in service.
  • Data you enter in the AI tools: business name and type, city, country, services, promotion text, website address, plus the generated content and your favourites. Please do not enter other people's personal data in these fields.
  • Security data: IP address and email when you request a password reset or a new verification email (abuse prevention).
  • Technical data: a session cookie and server logs containing your user ID and a masked email (e.g. v***@gmail.com). Logs never contain full emails, passwords, tokens or verification/reset links.
  • AI quality monitoring: if an AI answer is not in your chosen language, we store a snippet of up to 500 characters of the rejected answer, the tool, the language and your user ID. Your input text is not stored there.

We do not collect payment data, phone numbers, postal addresses or sensitive data.

We do not use advertising or behavioural tracking tools. Our hosting provider's network (Cloudflare, via Emergent) may collect aggregated, anonymous visit statistics (Cloudflare Web Analytics), which, according to Cloudflare, does not use cookies.

Providing your email is required to create an account; without it we cannot provide the service. All other data is optional.
