Terms of Use

Abyssos Last updated: July 28, 2026

These Terms of Use ("Terms") govern your use of Abyssos (the "App"), a personal household financial estimation application published by Shipping Trains L.L.C. ("Shipping Trains," "we," "us," or "our").

By downloading, accessing, or using the App, you agree to these Terms. If you do not agree, do not use the App.

Our Privacy Policy is available at: https://shippingtrains.com/apps/abyssos/privacy/

1. Who We Are

Abyssos is published by:

Shipping Trains L.L.C.
Email:

2. The Service

Abyssos helps you organize household financial information you enter yourself and generate planning estimates (such as cash flow, savings trajectories, debt payoff timing, and financial independence projections).

Abyssos:

You are solely responsible for the accuracy of information you enter and for any decisions you make based on the App.

3. Eligibility

You must be at least 13 years old (or the minimum age required in your jurisdiction) to use the App. If you are under the age of majority where you live, you may use the App only with permission of a parent or legal guardian.

4. Your Account and Apple Services

Abyssos does not require a separate Shipping Trains account. Purchases, Family Sharing, iCloud sync, and household sharing use your Apple ID and Apple services.

Your use of Apple services is also governed by Apple's applicable terms (including Apple Media Services Terms and iCloud terms).

5. Free Tier and Abyssos Premium

5.1 Free use

The App may be downloaded and used without charge under Free tier limits. Free limits may include caps on the number of income sources, assets, expenses, liabilities, projects (goals), and replacements, and may exclude multi-user household collaboration.

Linked items created with an asset (such as financed debt, a linked expense, or linked income) may not count as separate Free-tier objects toward those limits.

5.2 Premium features

Abyssos Premium may unlock:

Feature availability may change over time. We will describe material Premium benefits in the App and on the App Store product pages.

5.3 Purchases through Apple

All payments for Abyssos Premium are processed by Apple through In-App Purchase. We do not collect or store your payment card information.

Available purchase options may include:

Exact prices are shown in the App / App Store at the time of purchase and may vary by region and currency.

5.4 Subscriptions (auto-renewal)

If you purchase a subscription:

Unused portions of a free trial (if offered) may be forfeited when you purchase a subscription, where permitted by Apple.

5.5 Lifetime unlock

A Lifetime purchase is a non-consumable In-App Purchase that unlocks Premium features for as long as we continue to offer Abyssos and support that entitlement on your Apple ID, subject to these Terms and Apple's rules. Lifetime does not guarantee the App will remain available forever or that features will never change.

5.6 Restore Purchases and Family Sharing

You may restore eligible purchases on devices signed in with the same Apple ID using Restore Purchases in the App.

If Family Sharing is enabled for a product and the purchaser allows sharing, eligible family members may receive Premium access under Apple's Family Sharing rules. Family access depends on Apple's systems and the purchaser's settings; we do not control Family Sharing independently of Apple.

5.7 Refunds

Refund requests are handled by Apple under Apple's refund policies. Contact Apple Support for purchase refunds.

6. Household Sharing and Collaboration

If you use Premium collaboration features:

Share only with people you trust. You are responsible for whom you invite.

7. Your Content and Data

You retain ownership of the information you enter into Abyssos ("Your Content").

You grant us no license to collect or use Your Content on our servers, because Abyssos is designed so Your Content remains on your device and/or in your private Apple iCloud account (and with people you choose to share with).

You are responsible for:

8. Acceptable Use

You agree not to:

9. Intellectual Property

The App, including its design, software, trademarks, and branding (including "Abyssos"), are owned by Shipping Trains L.L.C. or its licensors and are protected by intellectual property laws.

Subject to these Terms, we grant you a personal, non-exclusive, non-transferable, revocable license to use the App on Apple devices you own or control, as permitted by the App Store terms.

10. Third-Party Services

The App relies on third-party services we do not operate. Today that includes Apple (App Store, StoreKit, iCloud/CloudKit, and push notifications) and, when you use non-USD household currency features, Frankfurter for optional exchange-rate reference data.

An on-device Apple Intelligence assistant, and optional web search via providers such as DuckDuckGo and Wikipedia, may be offered in a future update. Those features are not part of the current shipping experience; if we enable them, we will describe how they work in the Privacy Policy.

Those third-party services are governed by their own terms and privacy policies. We are not responsible for services we do not control.

11. Disclaimers

Planning estimates are illustrative only. We do not warrant that projections, calculations, syncing, notifications, AI outputs, or any other App features will be accurate, complete, uninterrupted, or error-free.

12. Limitation of Liability

Some jurisdictions do not allow certain limitations; in those places, our liability is limited to the fullest extent permitted by law.

13. Indemnity

To the maximum extent permitted by law, you agree to indemnify and hold harmless Shipping Trains L.L.C. from claims, damages, losses, and expenses (including reasonable attorneys' fees) arising out of your misuse of the App, your Content, your sharing of household data, or your violation of these Terms or applicable law.

14. Changes to the App and Terms

We may update the App, Premium features, Free limits, pricing (via the App Store), and these Terms from time to time. When we update these Terms, we will revise the "Last updated" date and post the current version at https://shippingtrains.com/apps/abyssos/terms/.

Continued use after changes become effective constitutes acceptance of the updated Terms, except where additional consent is required by law.

15. Termination

You may stop using the App at any time by deleting it.

We may suspend or stop offering the App or particular features. If Premium access ends (for example subscription expiration, refund, or revocation), Free-tier limits may apply again. Existing data is not deleted solely because Premium ends, but collaboration/sharing may stop as described above.

16. Governing Law

These Terms are governed by the laws of the State of Ohio, USA, excluding conflict-of-law rules, unless mandatory consumer protections in your place of residence provide otherwise.
