Savyn Privacy Policy

Effective as of July 11, 2026

This policy explains what data the Savyn application (the “App”) collects, how that data is used, and the control you have over it. Savyn is developed by Savyn(“we”, “us”). Questions can be sent to jonathansalendah.work@gmail.com.

1. Two ways to use the App

without an account, your data lives only on your phone. With an account, data is stored on our servers so it can be backed up.

Guest Mode (no account)

You can use Savyn without signing up. In this mode all financial data (accounts, transactions, categories, budgets, savings goals) is stored only locally on your device and is not sent to our servers. The only data still transmitted is application crash reports, as described in section 2. AI features (chat, voice, receipt scan) are not available in guest mode.

Account Mode (Google sign-in)

If you sign in with a Google account, your financial data is stored on our servers so it can be backed up and synced, and the AI features become active. When you switch from guest mode to account mode, your local data is uploaded to the server; we do not delete the local copy.

2. Data we collect

only data you provide yourself: basic identity from Google, the financial records you enter, and the voice/photos you submit for AI processing. We never access your bank accounts, location, contacts, or SMS.

Account data: email address, name (optional), and profile photo (optional, chosen by you from your gallery). Authentication uses Google Sign-In managed by Supabase Auth.
Financial data you enter: financial accounts (name, type, balance), transactions (amount, category, merchant, notes, date), budgets, and savings goals. Savyn does not connect to bank accounts, e-wallets, or any external financial source; all financial data comes from your own input.
Voice recordings: when you use voice input, the audio is uploaded to our servers to be transcribed and extracted by AI models. The audio file is deleted from our storage as soon as processing finishes, whether it succeeds or fails. The transcript and extraction results are kept as part of your logging history.
Receipt photos: when you use the receipt scan feature, the photo is uploaded for extraction by AI models. The photo file is deleted from our storage as soon as processing finishes. The extraction results are kept.
AI chat history:your messages and the assistant’s replies are stored so conversations can be resumed. You can delete conversation history from inside the App.
Crash reports: if the App encounters an error, a technical report is sent automatically through Sentry to help us fix bugs. This also applies in guest mode.

What we do not collect: location, contacts, SMS, call logs, or anything on your device beyond what is listed above. The App carries no ads and uses no advertising SDKs. The current version also does not use behavioral user analytics.

3. Device permissions and their purpose

Microphone: active only while you hold the record button for voice input.
Camera: used only when you use the receipt scan feature.
Photo gallery: used only when you pick a profile photo.
Notifications: the daily reminder is local to your device (not a server push) and can be turned off anytime in the App settings.

4. How data is used

Your data is used only to:

display and manage your own financial records;
process voice, chat, and receipt-photo input into transaction drafts through AI models;
provide backup and sync across devices (account mode);
fix bugs and keep the service secure.

We do not sell your data, do not share it for advertising, and do not use it to train AI models.

5. Third-party processors

we rely on a number of infrastructure services to run Savyn. They process data on our instructions.

Google (Google Sign-In): account sign-in.
Supabase: authentication and database storage.
Fly.io: API servers, located in the Singapore region.
Cloudflare R2: file storage (profile photos; voice audio and receipt photos temporarily during processing).
Upstash: processing queue infrastructure.
OpenRouter: AI processing. Voice audio, transcripts, chat messages, and receipt images are forwarded to AI model providers to be processed and produce the output you requested.
Sentry: crash report collection.

Some processing and storage takes place outside Indonesia (including Singapore). We choose providers with industry-standard security and apply reasonable safeguards for those transfers.

6. Security

We apply encryption in transit (HTTPS/TLS), token-based authentication, encrypted session storage on the device, data-ownership checks on every server request, and request rate limiting. No system can guarantee absolute security, but we work to protect your data to a reasonable standard and keep improving it.

7. Data retention

Account data and financial data are kept for as long as your account is active.
Voice audio and receipt-photo files are deleted from storage as soon as AI processing finishes.
Crash reports follow Sentry’s retention policy.
After you delete your account, all of your data is permanently removed as described in section 8.

8. Your rights and controls

you can edit your data, delete chat history, and delete your entire account directly from inside the App, no need to contact us.

Permanent account deletion:available inside the App (Profile > Delete Account). This removes all of your financial data, chat history, stored files, and your authentication account. The action cannot be undone.
Delete AI chat history from inside the App.
Correct or change financial data anytime from inside the App.
Revoke device permissions (microphone, camera, notifications) through your operating system settings.
For other requests concerning your personal data, contact jonathansalendah.work@gmail.com.

9. Age restriction

Savyn is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has provided us with data, contact us so it can be deleted.

10. Changes to this policy

This policy may be updated from time to time. Material changes will be announced through the App or this page, with an updated effective date. Continued use after a change means you accept the new policy.
