End User License Agreement (EULA)For the Keel iOS app (Chinese name: 司元)Effective: July 28, 2026Last updated: July 28, 2026
The short version
This agreement is between you and gwongsam, an independent developer. Apple is not a party to it and is not responsible for the App.
The App is a bookkeeping and reporting tool. It is not financial, investment, tax, or legal advice. Every figure comes from what you entered, and verifying it is your responsibility.
Membership is available as monthly and yearly auto-renewing subscriptions and as a one-time lifetime purchase. Subscriptions renew automatically; see Section 3 for how to cancel.
Your data is always yours. Expiry or downgrade never locks what you have already recorded — it stays readable, exportable, and backup-able.
Backups are your responsibility. Export them regularly; we cannot recover data for you.
1. Acceptance
These Terms of Service, which also constitute the End User License Agreement (this "Agreement"), form a binding agreement between you and gwongsam, an independent developer ("we", "us"), concerning Keel (Chinese name 司元, the "App").
By downloading, installing, or using the App, you confirm that you have read, understood, and agree to be bound by this Agreement and the Privacy Policy. If you do not agree, do not use the App and please delete it from your device.
This Agreement is concluded between you and us. Apple is not a party to it and bears no responsibility for the App or its content. See Section 14 for related provisions.
2. License grant and scope
Subject to your compliance with this Agreement, we grant you a personal, non-exclusive, non-transferable, revocable license to use the App on Apple-branded devices that you own or control, for your personal or household, non-commercial bookkeeping and financial record-keeping. The scope of this license is further subject to the Usage Rules in the Apple Media Services Terms and Conditions, including provisions on Family Sharing and volume purchasing.
The App is licensed, not sold, to you. All rights not expressly granted here are reserved.
3. Membership, subscriptions, and purchases
3.1 Free and membership tiers
The App's core bookkeeping capabilities — including double-entry recording, the account system, and the balance sheet, income statement, and cash flow statement — are free and unlimited in record count. Certain advanced features (such as cross-device sync and collaboration, forward-looking forecasts and analysis, heavier financial instruments like loans and buy-now-pay-later, and online market and exchange rate data) require membership. The current allocation of features is as shown in the App and may be adjusted across versions.
3.2 Products
Membership is sold through Apple's App Store in the following forms:
Product
Type
Term
Keel Premium · Monthly
Auto-renewing subscription
1 month, renews automatically
Keel Premium · Yearly
Auto-renewing subscription
1 year, renews automatically
Keel Premium · Lifetime
One-time purchase (non-consumable)
Pay once, no renewal
Prices are those displayed in the App and on the App Store for your region at the time of purchase, and may vary by region, currency, and taxes. We may change prices; a change does not affect a purchase you have already completed, and subscription price changes are notified — and where required, consented to — according to Apple's rules.
3.3 Auto-renewal, billing, and cancellation
For auto-renewing subscriptions:
Payment is charged to your Apple ID account upon confirmation of purchase.
The subscription renews automatically unless auto-renewal is turned off at least 24 hours before the end of the current period.
Your account is charged for renewal within 24 hours prior to the end of the current period, at the renewal price.
After purchase, you can manage the subscription and turn off auto-renewal in Settings › Apple ID › Subscriptions on your device.
Cancelling during an active paid period does not take effect immediately and is not refunded pro rata; your membership continues until the end of that period.
Where a free trial is offered, any unused portion of it is forfeited when you purchase a subscription.
3.4 Refunds
All purchases are processed by Apple, and refunds are granted by Apple at its discretion under its own policies. We cannot issue refunds directly. To request one, contact Apple at reportaproblem.apple.com. This section does not affect any statutory rights you have under applicable consumer protection law.
3.5 Restoring purchases
After changing devices or reinstalling, use "Restore Purchases" on the membership screen to restore entitlements associated with the same Apple ID.
3.6 Your data is never held hostage
We commit, as a term of this Agreement, that whatever the state of your membership, the data you have already recorded remains readable, exportable, and backup-able. When a membership expires or is cancelled, we only close the entry points for creating or enabling the corresponding features; existing records, accounts, and reports continue to be calculated and displayed normally. Capabilities that protect the correctness of your data — validation, backup, and export — are free permanently.
4. Your data and your backups
Accuracy is your responsibility. The App faithfully records and computes what you enter. Errors in amounts, dates, categories, exchange rates, or interest rates produce incorrect reports, and we are not responsible for that.
Backups are your responsibility. The App provides backup export; please export regularly and store the files safely. Because we do not hold your data (see the Privacy Policy), if your device is damaged, lost, or reset, or you delete data by mistake, we cannot recover it for you.
Securing backup files is your responsibility. A backup exported without a passphrase is an unencrypted file that anyone who obtains it can read. For an encrypted backup, a forgotten passphrase cannot be recovered — we neither store nor can reset it.
iCloud Sync depends on Apple's services. Its availability, speed, and storage quota are controlled by Apple. Insufficient iCloud storage, account problems, or service outages may pause syncing, and we are not responsible for that.
5. Shared books
You may share a book with others and set each member's permission to read-only or read-write. Initiating sharing means you authorize that person to access the contents of that book, including its transactions and attachments.
You are responsible for who you invite. Share only with people you trust. What a member views, copies, or exports while they have access is beyond our technical control.
You may remove a member or stop sharing at any time, but you cannot retract information they already obtained.
Turning off iCloud Sync and deleting the cloud copy ends all sharing you have initiated.
Members of a shared book are bound by this Agreement. You may not use the sharing feature to collect or disseminate other people's personal information.
6. Important: this app is not professional advice
The App is a record-keeping and reporting tool. It is not a financial adviser, an accountant, a tax preparer, or an investment adviser.
Every report, ratio, chart, forecast, and reminder the App produces is for your personal reference only. None of it constitutes financial, investment, tax, accounting, legal, or other professional advice, nor an offer, solicitation, or recommendation.
Forward-looking features (liquidity runway, net worth outlook, trend estimates, and similar) are mathematical projections from the history you entered and the assumptions you set. They are not promises or guarantees about the future, and actual outcomes will almost certainly differ.
Exchange rates and market data come from public sources and may be delayed, interrupted, or inaccurate. They are for bookkeeping conversion only and are not a quote; do not rely on them for actual trades, currency exchange, or valuation.
Reports generated by the App are not audited and are not formal financial statements compliant with any accounting standard or tax law. They should not be used directly for tax filing, regulatory reporting, loan applications, or to evidence your financial position to third parties.
For significant financial decisions — investing, borrowing, tax filing — consult a qualified professional. Any decision you make based on the App's output is yours alone.
7. Acceptable use
You agree not to:
reverse engineer, decompile, or disassemble the App, or attempt to derive its source code, except to the extent expressly permitted by law;
copy, modify, rent, lease, lend, sell, or distribute the App, or create derivative works from it;
circumvent, defeat, or interfere with entitlement verification, payment mechanisms, or any technical protection measures;
use the App for unlawful activity, including money laundering, tax evasion, falsifying financial records, or disguising illicit proceeds;
enter or share another person's personal information in the App without their consent;
abuse the App or the iCloud services it depends on through automated means, or otherwise interfere with other users.
8. Intellectual property
The App and all of its components — including software code, interface design, icons, written content, and the names "Keel" and "司元" and related marks — are owned by us or our respective licensors and protected by copyright and other laws. This Agreement transfers no intellectual property rights to you.
Content you create in the App — books, transactions, notes, attachments — belongs to you. We claim no rights over it and make no use of it (see the Privacy Policy).
9. Changes to the service
We may add, modify, suspend, or discontinue features of the App at any time, including adjusting which features are free and which require membership. We will make reasonable efforts to avoid such changes harming entitlements you have purchased, and a completed one-time lifetime purchase will not be invalidated by a feature reorganization.
Some features depend on services provided by Apple (iCloud, CloudKit, the App Store). Those services are controlled by Apple, and we are not responsible for unavailability caused by their change, limitation, or discontinuation.
10. Disclaimer of warranties
To the maximum extent permitted by applicable law, the App is provided "AS IS" and "AS AVAILABLE", without warranty of any kind, express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.
We do not warrant that the App will be uninterrupted, error-free, or free of defects, nor that its calculations, forecasts, or data will be accurate in all circumstances or meet your particular requirements.
Some jurisdictions do not allow the exclusion of implied warranties, so the above may not fully apply to you; in that case such warranties are limited to the shortest period permitted by law. Non-waivable statutory rights you hold under local consumer protection law are unaffected.
11. Limitation of liability
To the maximum extent permitted by applicable law:
We are not liable for any indirect, incidental, special, punitive, or consequential damages arising from your use of or inability to use the App — including lost profits, lost business opportunities, data loss, or losses from financial decisions — even if we have been advised of the possibility of such damages.
Our total cumulative liability under this Agreement or relating to the App will not exceed the amount you actually paid us for the App in the 12 months preceding the event giving rise to the claim; if you have paid nothing, that cap is CNY 100.
These limitations do not apply to our willful misconduct or gross negligence, to liability for personal injury where such limitation is prohibited, or to any other liability that cannot be excluded by law.
12. Termination
You may terminate this Agreement at any time by deleting the App. We may terminate the license granted to you if you materially breach this Agreement. Upon termination you must stop using the App and delete your copies. Provisions on intellectual property, disclaimer of warranties, limitation of liability, and governing law survive termination.
Termination does not affect your ability, under Section 3.6, to export and back up your own data.
13. Governing law and disputes
This Agreement — its formation, validity, interpretation, performance, and the resolution of disputes under it — is governed by the laws of the mainland of the People's Republic of China (for this purpose excluding its conflict-of-law rules and excluding the laws of the Hong Kong SAR, the Macao SAR, and Taiwan).
Any dispute arising from or relating to this Agreement should first be resolved through good-faith negotiation. Failing that, either party may bring the dispute before a competent People's Court at the developer's place of domicile.
If mandatory law in your place of residence gives you the right to bring proceedings in your local courts or to have local law apply, this section does not affect those rights.
14. Apple-specific terms
The following are included to satisfy Apple's minimum terms for a developer's EULA. You and we acknowledge and agree that:
Parties. This Agreement is concluded between you and us only, and not with Apple. We, not Apple, are solely responsible for the App and its content.
Scope of license. The license granted to you is as set out in Section 2 and is subject to the Usage Rules in the Apple Media Services Terms and Conditions.
Maintenance and support. We are solely responsible for providing maintenance and support for the App. Apple has no obligation whatsoever to furnish any maintenance or support services.
Warranty. We are solely responsible for any product warranties, whether express or implied. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you (if any). To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to any warranty are our sole responsibility.
Product claims. We, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your possession and use of it, including: (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, or similar legislation.
Intellectual property claims. In the event of any third-party claim that the App or your possession and use of it infringes that third party's intellectual property rights, we, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of such claim.
Legal compliance. You represent and warrant that (i) you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
Contact. Questions, complaints, or claims regarding the App may be directed to: gwongsam, independent developer, gwongsam@gmail.com.
Third-party terms. You must comply with applicable third-party terms of agreement when using the App (for example, the Apple Media Services Terms and the iCloud terms).
Third-party beneficiary. You and we acknowledge and agree that Apple and Apple's subsidiaries are third-party beneficiaries of this Agreement, and that upon your acceptance of this Agreement, Apple will have the right (and will be deemed to have accepted the right) to enforce this Agreement against you as a third-party beneficiary.
15. General provisions
Entire agreement. This Agreement and the Privacy Policy constitute the entire agreement between you and us regarding the App, superseding all prior oral or written communications.
Severability. If any provision is held invalid or unenforceable, the remaining provisions stay in effect, and that provision will be interpreted to achieve its original intent as nearly as lawfully possible.
Waiver. Our failure or delay in exercising any right under this Agreement is not a waiver of that right.
Assignment. You may not assign your rights or obligations under this Agreement without our written consent. We may assign this Agreement in connection with a transfer, merger, or reorganization of the business, without reducing the protections you have.
Changes to these terms. We may revise this Agreement. Revisions are published on this page with an updated date at the top, and material changes are surfaced prominently in the App. Continuing to use the App after a revision takes effect constitutes acceptance of it; if you do not accept, stop using the App and delete it.
