Privacy Policy
This Privacy Policy explains how the Vista mobile app ("we", "us", or "the app") handles your information. Vista is built with a local-first philosophy: your reading history, quiz answers, and daily-question records stay on your device unless you explicitly choose otherwise.
1. Summary in plain English
| What | Where it lives | Who can read it |
|---|---|---|
| News list, read status, quiz history, daily-question records, app settings | Your device only (Drift / SQLite) | Only you |
| Quiz history, daily-question records, language & reminder preferences | Synced to our cloud backup only if you manually enable cloud backup in Settings; protected by row-level security tied to your account ID | Only you (via your Apple ID) |
| Your current question, your input, and related news summaries when you use Sensemaking / news Q&A / Daily Question | Sent in real time to our DeepSeek backend proxy to generate the answer, then discarded | Vista (transit only, not stored) and DeepSeek (per their policy) |
| Public news cache (titles, short summaries, source links, publish time, category, importance score, AI analysis cards) | Stored in our cloud cache, not tied to any user identity | Readable by anyone using the app (anonymous read-only) |
We do not:
- Run third-party analytics SDKs that track you across apps
- Sell or share your data with advertisers
- Use your inputs to build a user profile
- Track you across Vista and Mira, or any other apps
- Store your AI conversations on our servers
2. Information we process
2.1 Stored locally on your device
All of the following are stored only on your device using a Drift (SQLite) database in the iOS app sandbox:
- News list and read status
- Quiz history (Today's Five Questions and per-article quizzes)
- Daily-question records
- Reminder schedule, app language, theme
- Subscription state cached from Apple
Apple's iOS file system encryption applies by default to all app data on your device.
2.2 Apple ID sign-in & optional cloud backup
Vista uses Sign in with Apple for identity and subscription restore. Sign-in does not automatically upload your learning history.
Only when you manually enable cloud backup in Settings, Vista syncs the following to our Supabase database so you can recover them after reinstall or on a new device:
- Quiz history
- Daily-question records
- Language and reminder preferences
Each cloud record is tied to your Apple account ID and protected by Supabase Row-Level Security (RLS) so only that account can read or write it. You can disable cloud backup or delete your synced data from Settings at any time.
2.3 Sent to AI provider (DeepSeek) in real time
When you use Sensemaking, ask a question about a news article, or answer Daily Question, Vista's backend (a Supabase Edge Function) sends the following to DeepSeek's API to compute the response:
- The current question or prompt
- Your written input
- Related news summaries (titles, short summaries) for context
DeepSeek's policy states that API content is not used for training and not stored beyond the request. We cannot guarantee any third party's behavior beyond their stated policy.
We do not store your AI inputs or outputs on our own servers. The Vista backend acts as a stateless transit layer between your device and DeepSeek, and applies basic per-hour rate limits to protect the service.
The app no longer provides a field for you to enter your own AI API key. All AI calls go through Vista's default DeepSeek backend proxy.
2.4 Public news cache
Vista's news cache (titles, short summaries, source links, publish times, categories, importance scores, and AI-generated analysis cards) is stored in our Supabase database to help new installs load faster.
This cache is publicly readable by the app (anonymous read-only) and is not tied to any user identity. It does not contain your reading history, quiz answers, or personal inputs.
3. Our servers
We use Supabase (hosted on AWS) to run:
- An Edge Function that proxies AI requests to DeepSeek (no content stored)
- The public news cache table (anonymous read-only)
- The optional cloud-backup tables for quiz history and settings, protected by row-level security and tied to your Apple account ID
We use DeepSeek as our AI provider. They process your messages in real time and (per their policy) do not store them.
We may switch or add AI providers (e.g., OpenAI, Anthropic) in future versions. We will update this policy if the provider changes.
4. Tracking and advertising
Vista does not use third-party analytics SDKs, ad networks, or cross-app trackers. Vista and Mira do not share data with each other — each app's data stays in its own scope.
5. Children's privacy
Vista is not intended for users under 13. We do not knowingly collect any data from children. If you believe a child has used the app, contact us and we will assist.
6. Your rights
- To delete on-device data: delete the app — all local data is removed immediately and permanently.
- To delete cloud-backup data: turn off cloud backup in Settings, or use the "Delete account" option to remove all cloud records tied to your Apple account.
- To opt out of AI processing: simply do not use Sensemaking, news Q&A, or Daily Question. Browsing news cards alone does not send any data to AI.
- For data export: contact us by email — we will export your cloud-backup records (if any) on request.
7. Copyright and news content
Vista is designed for learning and reflection. It does not provide full-text news redistribution. News cards prioritize titles, short summaries, source names, publish times, original analysis cards, and a link back to the original source.
The app does not actively scrape full article pages. If an RSS source provides longer content, Vista compresses it into short summaries and context snippets. Full reading should happen on the original site.
News titles, summaries, images, and links belong to their original publishers. Rights holders can email us with the title, source, and requested action.
8. Changes to this policy
If we materially change how data is handled, we will:
- Update the date at the top
- Notify you in-app at next launch
- (For breaking privacy changes) Prompt you to re-accept
9. Disclaimer
Vista provides AI-generated analysis of news as a learning aid. AI output may be wrong, incomplete, or over-summarized. For finance, medical, legal, public safety, or other important decisions, refer to original sources and professional advice.
