Privacy Policy
This Privacy Policy explains how PlainBetter handles personal information when you use plainbetter.co.uk. PlainBetter is currently an independent UK-based project in an early testing stage.
1. Information we process
Account information
If you create an account, we process your email address, account identifier and authentication/session information. Authentication is provided by Supabase. PlainBetter does not receive or store your password in plain text.
Language-learning information
For logged-in users, we may store learning information such as your language, vocabulary lemmas, successful-use counts, successful Hardcore-test recalls and recorded chat-practice time.
Conversation content
When you use Chat or Generate Example Response, the text needed to provide the feature is sent to the PlainBetter backend and to OpenAI's API so a response can be generated. PlainBetter does not currently save full chat transcripts to your account database.
Recent Conversations on your device
If you choose to allow Recent Conversations, PlainBetter stores recent chat content in your browser's local storage. This is currently limited to 20 conversations and approximately 30 days. You can refuse or later withdraw this choice through Privacy choices in the footer.
Technical and security information
Our hosting, authentication, email and infrastructure providers may process technical information such as IP address, timestamps, request information, device/browser information and security logs as part of operating and protecting their services.
2. Why we use this information
We use personal information where it is needed to provide features you request, maintain your account and learning history, operate and secure the service, troubleshoot problems, prevent abuse, and communicate with you about authentication or account matters.
Where the law requires consent for optional storage on your device, such as the current Recent Conversations feature, we rely on your consent. You can withdraw that consent at any time.
3. Browser storage
PlainBetter uses essential browser storage for functions such as remembering authentication/session state when you choose to sign in and remembering your privacy choice. Optional Recent Conversations storage is disabled unless you allow it.
PlainBetter does not currently use advertising or behavioural-tracking storage technologies on the site.
4. Service providers
PlainBetter currently uses the following service providers:
- Supabase — authentication and database services.
- OpenAI — generation and analysis of language-learning conversations through the API.
- Render — backend hosting.
- Cloudflare — domain, DNS, frontend hosting and email routing.
- Resend — delivery of authentication-related email.
5. International processing
Some service providers operate internationally, so personal information may be processed outside the UK. Where applicable, transfers are handled using safeguards and contractual arrangements made available by those providers and required by data-protection law.
6. How long we keep information
- Optional Recent Conversations stored on your device are limited to approximately 30 days and 20 conversations.
- Account, vocabulary and learning-stat information is generally kept while your account remains active, unless you ask us to delete it or limited retention is reasonably required for legal, security or operational reasons.
- Infrastructure and provider logs may have separate retention periods set by the relevant provider.
7. Your rights
Depending on the circumstances, UK data-protection law may give you rights including access, correction, deletion, restriction, objection, data portability and withdrawal of consent.
To make a request, contact . You also have the right to complain to the UK Information Commissioner's Office if you are unhappy with how your personal information is handled.
8. Sensitive information
Please avoid putting unnecessary sensitive personal information, confidential information, or personal information about other people into your chat messages or custom scenarios.
9. Adults during the current beta
PlainBetter is currently intended for adults aged 18 or over during this early testing stage.
10. Changes to this policy
We may update this Privacy Policy as PlainBetter develops, particularly if we add new storage, analytics, advertising, payment or account-history features.
