Where your question goes

Saved to your account only
Called through their APIs. Not used for training.
Your data stays yours
Your chats are stored under your account and only you can read them, unless you choose to share a link. Your question goes to the providers of the models you pick. With two or more models, OpenAI models also write the combined answer and grade where the models agree, and OpenAI checks each question (and a long draft as you type) to suggest models and test web search; private mode skips that check unless you ask Synero to choose the models. Turn on private mode and a chat is not saved to your history at all.
Never used to train AI models
Synero does not use your questions or results to train any AI model. We call OpenAI, Anthropic, Google and xAI through their APIs, whose terms cover how API inputs are handled (see the provider notes below and our privacy policy).
Row-level security
Every piece of data (queries, responses, configurations, presets, ratings) is protected by row-level security policies. Only the authenticated owner can read or modify their own records.
Encrypted in transit and at rest
All communication between your browser and Synero is encrypted via TLS. Data at rest is stored in encrypted databases with Supabase's managed infrastructure.
Secure authentication
Synero uses Supabase Auth with support for email/password and social sign-in providers. Sessions are kept in cookies and refreshed automatically.
API key isolation
API keys are scoped to individual accounts and can be revoked at any time. Each key is hashed before storage. We never store plaintext API keys in our database.
Upstream AI providers
Synero sends your questions to four AI providers via their commercial APIs. Here is how each handles data:
OpenAI
Called through the OpenAI API, whose terms prohibit training on API inputs
Anthropic
Called through the Anthropic API under its commercial terms, which exclude API data from training
Gemini API calls are covered by Google's API terms and data policies
xAI
Grok API calls follow xAI's API terms of service
Infrastructure
- Hosted on DigitalOcean App Platform with automatic HTTPS
- Database and authentication powered by Supabase with managed PostgreSQL
- Payments handled by Whop. Synero never sees your card number
- Google Analytics, plus Google Ads, Meta and Whop pixels that count page views, sign-ups and your first free question, never its content (Whop's also sets a device identifier). Crisp runs the live support chat
