Bullion Note

Privacy Policy · Updated 2026-09-30

On this device first; saved to your account after sign-in

Bullion Note is a precious-metal ledger and everyday-money ledger. When you are not signed in, records stay in the app sandbox on this device. You do not need an account to record or view valuations.

On-device data includes the category, metal, weight, purity, cost, and note for a holding; ledger name, income or expense amount, category, date, time zone, and note in your life ledger; goals and budgets; and display, market, currency, unit, and other app settings. Gold-gram values shown for life-ledger entries are recalculated from market prices, and the original cash amounts are kept as entered.

Account data

After you sign in, holdings, ledgers, everyday entries, categories, goals and budgets, some settings, and photos attached to records are stored in your Bullion Note account. Data is encrypted in transit with HTTPS. At rest, it is encrypted by our cloud infrastructure provider, which manages the keys. Our servers keep each account's data separate. When you are not signed in, these records stay on this device only.

InCosmos KK entrusts this account data to a cloud infrastructure provider for processing. The provider acts as a processor. This data may be processed on servers outside your country or region (cross-border transfer). This processing is necessary to perform the account and multi-device sync service (performance of a contract).

These records are kept for as long as the account exists. When you delete a record, the account keeps a deletion marker (tombstone) so other signed-in devices can apply the same deletion. Deletion markers are retained and are not cleared on a short fixed schedule.

Separate internal safety copies are kept for support only and are not shown in the app. When the account receives new sync writes, one complete copy is saved per day. Complete copies from the last 14 days are kept, and the latest complete copy is always kept.

Deleting the account in the app clears synced records and photos in the account. All copies are removed within 30 days after account deletion. Signing out does not delete data in the account. Records on this device remain, and syncing stops. See Delete Account.

Optional account and alerts

You may choose Google or Apple sign-in. After sign-in, our servers store data needed to run the account: email address, display name, sign-in provider user ID, session records, and—if you enable alerts—device tokens, alert rules, and preferences. The bullionnote_session cookie lasts about 30 days. Network information needed to complete requests is also processed.

You can also sign in with an email code or link an email after signing in. Our email provider processes the recipient address and verification message to deliver the email. Our servers store only a check value for the code, along with temporary records of the email address, request time, verification attempts, and email and network-address hashes used to prevent abuse. Codes expire after 10 minutes. Related request records are removed within a day after they expire. A verified, linked email remains part of the account until account deletion. Verification emails are used only for account authentication.

Signing out does not clear local ledgers. Deleting an account removes server-side account identifiers, sessions, device tokens, alert rules, and preferences; related security audit records are de-identified. An anonymous deletion event and account deletion tombstone may be retained for security, abuse prevention, and data integrity. See Delete Account for details.

AI recognition

AI entry can turn typed text, voice, or an image (a receipt, bill screenshot, or precious-metal purchase document) into an entry draft. Sign-in is required.

Text, audio, and images are sent through our servers to third-party AI service providers and used only to recognize them and create entry drafts. Voice is first converted to text, then turned into a draft. We do not keep images, audio, or transcripts. A recognized draft is held on our servers so it can be recovered if the connection drops. It is deleted once you confirm or cancel it; a draft left unhandled is deleted automatically after 7 days. After you review a draft, it is added to your ledger and synced with your account.

Before you use image or voice recognition for the first time, the app asks for your consent. Your choice is recorded with your account on our servers, and you can withdraw it in Settings › Privacy & security › AI recognition. After you withdraw, images and voice are not sent until you consent again. Typed text is also sent to third-party AI services, but the app does not ask for separate consent before typed recognition. You can always record entries by hand instead.

This content may be processed on servers outside your country or region (cross-border transfer). We use these services only to perform recognition and do not use your content to train models.

To manage quotas and prevent abuse, we keep usage records such as recognition type, status, number of drafts, and time, and for voice, the duration, status, and language. These records contain no image, audio, or text content and are kept for 90 days. Weekly usage totals are kept for up to about 13 months. These records are deleted when you delete your account.

Quotes and export files

Market quotes are fetched through Bullion Note's servers. Quote requests include the market, currency, unit, and network information needed to complete the request, but do not include your metal holdings or life-ledger entries. Home-screen widgets fetch quotes from a public endpoint; these requests carry no account information and no holdings data.

You can export a file when you choose to. The app creates bullion-note-backup.zip. An export may include metal ledgers, life ledgers, categories, alerts, and settings. It is handed to the system share sheet so you choose where to save or send it. After export, the selected destination or service governs how the file is kept and processed.

Use, retention, and your choices

We use the data above to provide sign-in, sessions, AI recognition, quotes, alerts, account sync, export, and support; to secure the service; and to troubleshoot issues. Bullion Note does not sell personal data or use personal data for cross-service advertising tracking.

Local data remains until you clear it in the app or system, or uninstall the app. Account-operation data remains until account deletion or until it is no longer needed for the purposes above. De-identified records may be retained where needed for legal, security, or abuse-prevention purposes.

In the app, you can review account status, export a file, sign out, or delete the account. If you cannot use the app, email hi@incosmos.art to request access, correction, or deletion of account data.

To complete revocation of third-party sign-in authorization, necessary encrypted credentials and associated identifiers may be temporarily retained for retries after a failure. They are deleted when revocation processing completes and are not used to restore a deleted account.

Updates and contact

We may update this policy as the product or legal requirements change. The revision date appears on this page, and material changes will be communicated through an appropriate in-product notice.
