SpanInsight is a privacy-first platform. Your data files (CSV, Excel, JSON) are processed entirely on your device. We do not upload, store, or have access to your data.
What We Process Locally
All data files you import are parsed and analyzed on your device
Charts and visualizations are rendered locally using Python (pandas, matplotlib)
AI-generated code executes in a sandboxed environment with no network or filesystem access
What Touches the Cloud
AI prompts only — when you ask a question, only the text prompt and a column summary are sent to the AI gateway. Raw data is never transmitted.
Form responses — if you create a survey, respondent answers are stored in a secure edge database linked to the form ID.
Shared reports — if you choose to share a report, the rendered content is uploaded to temporary secure storage and automatically deleted after 30 days.
Data Storage
Your UUID identity is stored locally in encrypted storage (AES-256 via platform keychain/keystore)
No account or email is required
Survey form schemas and responses are stored in a secure edge database
Shared reports are stored in ephemeral secure storage with a 30-day automatic deletion lifecycle
Third-Party Services
AI Inference — AI language models for prompt processing. Prompts are processed and not stored beyond the request lifecycle.
Ads — Google AdMob (mobile only) for optional ads. Subject to Google's privacy policy.
Your Rights
You can clear all local data at any time from Settings → Clear Data. To delete your survey forms and responses, delete them individually from the Forms tab. Since we don't have your email or identity, there is no account to delete.
