Abyssos ("the App," "we," "us," or "our") is a personal household financial planning app published by Shipping Trains L.L.C. This Privacy Policy explains what information the App handles, how it is stored, and the choices you have.
Our approach is simple: Abyssos is built to keep your financial data on your own devices and in your own private iCloud account. We do not operate servers that collect, store, or sell your personal or financial information.
1. Information You Enter
To create plans and projections, you enter household financial information into the App, which may include:
- Household and member names you choose
- Income sources and amounts
- Assets, account values, and growth/yield assumptions
- Investment holdings you may enter (tickers, share quantities, and cash)
- Expenses and recurring bills
- Liabilities (loans, debts) and payment details
- Savings and financial-independence goals and assumptions
If you use investment holdings, tickers, quantities, cash amounts, and other holdings fields you type are household data. They are stored with the household storage option you chose (on this device or in your iCloud), like other entries you make.
You decide what to enter. None of this information is required by us, and we never see it.
2. Where Your Data Is Stored
Abyssos stores the data you enter in one of two places, based on the storage option you choose for each household:
- On this device — data is kept in a local database on your device only.
- iCloud — data is synced through Apple's iCloud (CloudKit) to your own private iCloud account so it is available across your devices and can be backed up by Apple.
When you use iCloud storage or share a household with another person, that data is handled by Apple under Apple's Privacy Policy and iCloud terms. We do not have access to your iCloud data. We cannot read, recover, or restore it.
We do not transmit your financial data to any servers operated by Shipping Trains L.L.C., and we have no ability to access it.
On-device household backups
For households stored in iCloud, the App may keep a small number of recent copies of the local household database in Application Support on this device (for example, the last three snapshots). These files:
- Stay on this device
- Are included in an iPhone backup (Finder or iCloud Backup of the phone) if you use those
- Are not uploaded to Shipping Trains L.L.C.
- Are not a substitute for CloudKit sync and are not restored from inside the App in version 1.1
Manage Household shows when iCloud last exported successfully and when the latest on-device snapshot was written. “Syncing with iCloud” is only shown after a successful export.
3. Shared Households
If you choose to share a household with another person, that data is shared through Apple's CloudKit sharing to the people you invite. Those participants can view and, depending on permissions, edit the shared household. Only share with people you trust. Sharing is handled entirely by Apple's infrastructure; we do not receive a copy of the shared data.
4. Bring Your Own Key
You can use Abyssos without adding any keys. If you paste a FRED® API key or Tiingo API token in Settings → Bring Your Own Key:
-
The key or token is stored only in this device’s Keychain
(
WhenUnlockedThisDeviceOnly). It is not synced to iCloud, not included in iCloud Keychain, not shared with household members, and never sent to Shipping Trains L.L.C. - Removing the key in Settings, or deleting the App, removes it from this device.
-
FRED: the App sends only the series IDs it needs (for example mortgage rate series)
to
api.stlouisfed.orgusing your key. Observation values stay in memory for the current session and are not written to household storage or iCloud. -
Tiingo: the App sends only the ticker symbols you entered to
api.tiingo.comusing your token. Default pricing is end-of-day closes. If you choose Real-Time in Settings, quotes are requested from Tiingo’s IEX-derived endpoints (/iex). Quote values stay in memory for the current session and are not written to household storage or iCloud. - Tickers, quantities, cash amounts, and other holdings fields you type are household data. They sync with iCloud like other entries you make. Prices from Tiingo do not sync.
5. The AI Assistant (future update)
An on-device AI assistant may be available in a future update of Abyssos on devices that support Apple Intelligence. It is not part of the current shipping experience.
When enabled in a future release:
- The assistant is intended to run on your device using Apple Intelligence (Apple's on-device Foundation Models). Your financial figures would be processed locally and would not be sent to us.
- The assistant may optionally perform web searches for general reference information
(such as interest rates, market indices, or product details). Web search would be controlled by a setting
with three modes:
- Local Only (default): No queries leave the App.
- Sanitized: General reference queries (without your personal dollar amounts) may be sent to third-party search providers.
- Full Access: Your query, which may include financial figures, may be sent externally for more accurate results.
- When a web search runs, the query would be sent to third-party services (currently planned: the DuckDuckGo Instant Answer API and Wikipedia). Those services would receive only the search text the assistant generates and process it under their own privacy policies. We would not log or store these queries.
Until that feature ships, Abyssos does not send AI-related queries off device. We will update this Privacy Policy when the assistant becomes available.
6. Information We Do Not Collect
We want to be explicit. Abyssos does not:
- Collect or store your personal or financial data on our servers
- Use third-party analytics or advertising SDKs
- Track you across apps or websites
- Sell, rent, or share your information with data brokers
- Require an account, email address, or login with us
- Connect to your bank or financial institutions
- Receive, store, or sync your Bring Your Own Key credentials — those stay on your device
7. Notifications
If you enable notifications, the App may send you local reminders. Push notifications related to iCloud sharing are delivered through Apple's services. You can manage or disable notifications in your device settings.
8. Exporting and Deleting Your Data
You are always in control of your data:
- Export: You can export your data from within the App at any time.
- Delete: Deleting a household or the App removes its local data from your device. For iCloud-stored data, deletion syncs through your iCloud account. Because the data lives in your iCloud, you can also manage it through Apple's iCloud controls.
- API keys: Removing a Bring Your Own Key entry in Settings, or deleting the App, removes that key or token from this device’s Keychain.
9. Children's Privacy
Abyssos is not directed to children under the age of 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect information from children. Because we do not collect personal information at all, no such information is gathered through normal use.
10. Security
Data stored locally is protected by your device's security features. Data stored in iCloud is protected by Apple's security and encryption. Because we do not hold your data, the security of your information depends on the protections you keep on your device and Apple account (such as a passcode, Face ID/Touch ID, and two-factor authentication).
Optional Bring Your Own Key credentials are stored only in this device’s Keychain with
WhenUnlockedThisDeviceOnly accessibility, as described in section 4.
Optional App Lock
You can optionally require authentication to open the App after it has been in the background. This feature is off by default and can be turned on in Settings under Security.
When enabled, Abyssos uses Apple's LocalAuthentication framework and the device Keychain to verify your identity using Face ID, Touch ID, or your device passcode. We do not collect, receive, store, or transmit biometric data (such as face maps or fingerprint images). Biometric templates remain in your device's Secure Enclave and are managed entirely by Apple under Apple's Privacy Policy.
Your app lock preference and grace-period settings are stored locally on your device (UserDefaults) and are not synced to iCloud or to any servers operated by Shipping Trains L.L.C. Enabling app lock creates a small, device-only Keychain entry used solely to verify unlock; it contains no household or financial data. If you change biometric enrollment on your device, you may need to turn app lock off and on again in Settings.
11. Third-Party Services
The App relies on the following third parties only as described above:
- Apple (iCloud/CloudKit storage and sync, push notifications, App Store / In-App Purchase, device Keychain, and — in a future update if enabled — Apple Intelligence on-device AI) — see Apple's Privacy Policy.
- Frankfurter (frankfurter.app / api.frankfurter.dev) — optional exchange-rate reference data when you use non-USD household currency features.
- FRED® (api.stlouisfed.org) — only if you add your own FRED API key under Bring Your Own Key; the App sends series IDs needed for features such as mortgage-rate reference data.
- Tiingo (api.tiingo.com) — only if you add your own Tiingo API token under Bring Your Own Key; the App sends ticker symbols you entered for end-of-day or optional real-time (IEX-derived) quotes.
- DuckDuckGo and Wikipedia — only if and when a future AI web-search mode is enabled, and only for the search text that feature generates.
We have no business relationship in which your personal data is transferred to us by these services.
12. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above and make the current version available in the App and/or our distribution listing. Continued use of the App after an update means you accept the revised policy.
