Terms of Use

1. Acceptance

These Terms of Use (“Terms”) are an agreement between you and Caner Gulay, the individual developer of Stowbook (“we”, “us”, “the developer”). They govern your use of the Stowbook app for iPhone and iPad, including its widgets and Siri and Shortcuts actions, its server features and this website (together, “Stowbook” or “the app”). By downloading, installing or using Stowbook you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the app.

If you obtained the app from the Apple App Store, Apple’s Licensed Application End User License Agreement (the “Standard EULA”) also applies. These Terms supplement it; if they conflict, these Terms govern to the extent permitted, and section 20 always applies.

2. Who may use Stowbook

You must be at least 18 years old, or the age of majority where you live, and able to enter into a binding contract. If you use Stowbook on behalf of a business or other organization, you confirm that you are authorized to accept these Terms for it, and “you” includes that organization.

3. What Stowbook is, and is not

Stowbook helps you keep your own records of things you own, stock or store: it stores the information you enter or scan, organizes it by place, counts quantities, reminds you when stock is low, and produces labels, lists and reports from your data.

STOWBOOK IS A RECORD-KEEPING TOOL ONLY. IT IS NOT AN APPRAISAL OR VALUATION SERVICE, AN INSURANCE PRODUCT OR ADVICE, AN ACCOUNTING, BOOKKEEPING, TAX OR AUDIT SYSTEM, A POINT-OF-SALE OR COMPLIANCE SYSTEM, OR LEGAL, FINANCIAL OR PROFESSIONAL ADVICE OF ANY KIND. NOTHING IN THE APP, INCLUDING A QUANTITY, A VALUE, A TOTAL, A STOCK STATUS, AN AI IDENTIFICATION OR ESTIMATE, OR A REPORT, IS A STATEMENT BY US THAT IT IS ACCURATE, COMPLETE OR FIT FOR ANY PURPOSE.

Reports and exports, including the insurance home inventory report, are summaries of information you supplied or accepted. They are not certified, verified or endorsed by us, and whether an insurer, tax authority, court, buyer or anyone else accepts them is entirely up to them.

4. Your responsibilities

You acknowledge and agree that you are solely responsible for:

• The accuracy and completeness of everything you enter, scan, import, accept or edit, including quantities, places, prices, costs, values, barcodes and serial numbers.
• Your stock, purchasing, pricing, sales and other business decisions, and for checking physical stock against your records.
• Your insurance: understanding your policy, deciding what to record, keeping the evidence your insurer requires (such as receipts, photos and appraisals), and preparing and making any claim.
• Your accounting, tax, customs, consumer protection, product safety and other legal obligations, which Stowbook does not perform for you.
• Keeping your own backups and copies of your data and of anything important, such as receipts and reports (section 6).
• Having the right to photograph, scan and record what you add, and handling any personal information of other people you add (for example on a receipt or in a note) lawfully.
• Not relying on low-stock reminders as your only means of tracking stock. Notifications can be delayed, disabled or missed.

5. AI features and estimates

AI photo, shelf and receipt scans use an artificial intelligence service (Google’s Gemini API) to suggest item details from an image you choose to submit. AI can misidentify products, brands and models, miscount items, misread receipts, and give values that are far from what an item is worth or would cost to replace. It is designed not to invent barcodes or serial numbers, but it may still be wrong. You must review every suggestion before saving it.

AI IDENTIFICATIONS AND VALUE ESTIMATES ARE AUTOMATED GUESSES PROVIDED FOR CONVENIENCE ONLY. THEY ARE NOT APPRAISALS OR VALUATIONS, AND THEY MUST NOT BE USED FOR INSURANCE, TAX, ACCOUNTING, LEGAL, LENDING, ESTATE, CUSTOMS OR ANY OTHER OFFICIAL OR FINANCIAL PURPOSE WITHOUT INDEPENDENT VERIFICATION BY YOU OR A QUALIFIED PROFESSIONAL. WE MAKE NO REPRESENTATION THAT ANY ESTIMATE REFLECTS MARKET, REPLACEMENT, RESALE OR INSURED VALUE.

By starting an AI scan you confirm that you have the right to submit the image and consent to the processing described in the Privacy Policy. Free AI scan allowances, the Pro fair-use limit (currently 300 scans a month), rate limits and the availability of AI features may change, and AI scans may be unavailable at times.

6. Your data, backups and iCloud

Stowbook stores your inventory on your device and, if you turn it on, syncs it through your own iCloud account, which Apple provides under its own terms. We do not hold a copy of your inventory and cannot recover, restore or repair it. Data can be lost or damaged through device loss or failure, deleting the app, iCloud being turned off, full or unavailable iCloud storage, sync conflicts between devices, software defects, imports or edits, or other causes. Export your data regularly (for example to CSV or PDF) and keep backups. To the fullest extent permitted by law, we are not responsible for any loss, corruption or disclosure of your data.

7. Your content

You own the information, photos and other content you put into Stowbook. You grant us a limited, worldwide, royalty-free license to process content you send to our server (such as an image you scan with AI) solely to provide the requested feature, as described in the Privacy Policy. You are responsible for your content and for having the rights to it. If you send us feedback or suggestions, we may use them freely and without obligation to you.

8. Acceptable use

You must not, and must not help others to:

• use Stowbook for anything unlawful, including tracking stolen, counterfeit or illegal goods, or to defraud an insurer or anyone else;
• submit images or content that are unlawful, infringing, sexually explicit, or that contain other people’s personal information without a lawful basis;
• access our server other than through the app, including by scripts, bots or scraping, or use it to build a competing product or dataset;
• circumvent or tamper with scan allowances, rate limits, fair-use limits, DeviceCheck, subscription checks or other security or usage controls;
• interfere with, overload or probe the service, or introduce malicious code;
• resell, rent, sublicense or commercially redistribute the app or its server features.

9. Subscriptions, trials and purchases

• Stowbook is free to download with optional Stowbook Pro, sold through Apple’s App Store as an auto-renewing subscription (for example monthly or yearly) or a one-time lifetime purchase. Current prices are shown in the app and the App Store before you buy, in your local currency.
• Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically at the then-current price for the same period unless cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
• Free trial. Where a free trial is offered (for example, 7 days on the yearly plan), the subscription starts and you are charged when the trial ends unless you cancel at least 24 hours before it ends. Any unused part of a trial is forfeited when you buy a subscription, where applicable. Trials are offered once per Apple Account, as Apple determines.
• Cancel any time in your device’s Settings → your name → Subscriptions, or in the App Store. Cancellation takes effect at the end of the current period; you keep Pro until then. Deleting the app does not cancel a subscription.
• Lifetime. A lifetime purchase gives you Pro features for as long as we offer Stowbook and those features, not for your lifetime or any fixed period. It is subject to the same fair-use limits, and server features such as AI scans depend on third-party services that may change or end (section 13).
• Refunds are handled by Apple under its policies (reportaproblem.apple.com). We cannot issue refunds for App Store purchases. Nothing here limits refund or withdrawal rights you have under mandatory law.
• We may change prices and what is included in Free or Pro. Price changes apply from your next renewal, with notice as Apple requires. Your data stays on your device and in your iCloud whether or not you subscribe.

10. License

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use Stowbook on Apple-branded devices that you own or control, as permitted by Apple’s Usage Rules, including Family Sharing where enabled. You must not copy, modify, translate or create derivative works of the app, or reverse engineer, decompile or disassemble it, except to the extent the law expressly allows despite this restriction. We and our licensors keep all rights not expressly granted, including all rights in the app, its design, code and content.

11. Third-party services

Stowbook relies on services we do not control, including Apple (App Store, payments, DeviceCheck, iCloud, Siri and on-device intelligence), Google (Gemini API), RevenueCat (subscriptions), and our hosting and network providers. Their availability, accuracy and terms are their own, and we are not responsible for them. Links to third-party websites are for convenience only.

12. No affiliation; trademarks

Stowbook is an independent product. Product names, brands and other trademarks that appear in the app, in AI suggestions or on this website belong to their respective owners and are used only to identify products; their appearance does not imply any affiliation or endorsement. Label templates are described by sheet format only. Apple, iPhone, iPad, iCloud, Siri and App Store are trademarks of Apple Inc.

13. Changes to the app

We may update, change, suspend or discontinue any part of Stowbook, including server features such as AI scans, at any time, with or without notice. We will try to give reasonable notice of material changes to paid features. Some updates may be required to keep using server features. Features described as beta or preview are provided for evaluation and may be less reliable.

14. Disclaimer of warranties

TO THE FULLEST EXTENT PERMITTED BY LAW, STOWBOOK AND ALL INFORMATION, IDENTIFICATIONS, ESTIMATES, CALCULATIONS, TOTALS, REMINDERS, LABELS, REPORTS, EXPORTS, SYNC AND OTHER CONTENT AND FEATURES IT PROVIDES ARE PROVIDED “AS IS” AND “AS AVAILABLE”, WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTIES OF MERCHANTABILITY, SATISFACTORY QUALITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, COMPLETENESS, TIMELINESS, QUIET ENJOYMENT AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, SECURE OR FREE OF DATA LOSS, THAT SYNC WILL BE RELIABLE, THAT ANY AI IDENTIFICATION OR VALUE IS CORRECT, THAT ANY REPORT WILL BE ACCEPTED BY AN INSURER OR ANYONE ELSE, OR THAT DEFECTS WILL BE CORRECTED. NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED FROM US OR THROUGH THE APP CREATES ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS. YOU USE STOWBOOK AT YOUR OWN RISK.

15. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW:

• IN NO EVENT WILL THE DEVELOPER BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, SALES, BUSINESS, GOODWILL, USE OR DATA, OR FOR COSTS OF SUBSTITUTE GOODS OR SERVICES, ARISING OUT OF OR RELATING TO THESE TERMS OR STOWBOOK.
• WITHOUT LIMITING THE ABOVE, THE DEVELOPER WILL NOT BE LIABLE FOR: ANY LOST, CORRUPTED, UNSYNCED OR DISCLOSED DATA, PHOTOS OR RECORDS; ANY STOCK LOSS, SHRINKAGE, OVERSTOCK, STOCKOUT, MISCOUNT, SPOILAGE OR MISPLACED ITEM; ANY PRICING, PURCHASING OR SALES DECISION; ANY INSURANCE CLAIM THAT IS DENIED, REDUCED OR DELAYED, OR ANY UNDERINSURANCE; ANY TAX, ACCOUNTING OR REGULATORY CONSEQUENCE, FINE OR PENALTY; OR ANY RELIANCE ON AN AI IDENTIFICATION, VALUE ESTIMATE, TOTAL, REPORT OR REMINDER.
• THE DEVELOPER’S TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR STOWBOOK WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID FOR STOWBOOK IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) USD 50.

These limitations apply to any theory of liability, whether in contract, tort (including negligence), strict liability, product liability or otherwise, even if we were advised of the possibility of such damages and even if a remedy fails of its essential purpose. They are an essential basis of the bargain between you and us; Stowbook would not be offered on these terms without them.

Some jurisdictions do not allow certain warranties to be excluded or liability to be limited. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, such as liability for death or personal injury caused by our negligence where the law forbids excluding it, for fraud, or for gross negligence or willful misconduct where the law so provides, and nothing affects your statutory rights as a consumer, including your rights under consumer law in the European Union and the United Kingdom, the consumer guarantees under the Australian Consumer Law, and the New Zealand Consumer Guarantees Act where they apply. Where such law applies, our liability is limited to the minimum extent that law permits.

16. Indemnification

To the extent permitted by law, you will defend, indemnify and hold harmless the developer from and against any claims, demands, losses, liabilities, damages, costs and expenses (including reasonable legal fees) brought by a third party, including any customer, supplier, buyer, partner, employee, insurer or authority, arising out of or relating to: your business, goods, stock or sales; any insurance claim or other submission you make using information from Stowbook; your use of or reliance on Stowbook; records, reports, labels or information you create, share or provide with it; your content; or your breach of these Terms or of any law. We may take part in the defense of any claim with counsel of our choice at our own cost.

17. Termination

You may stop using Stowbook at any time by deleting it and cancelling any subscription. We may suspend or end your access to server features if you breach these Terms, abuse the service, or where required by law. Sections 3 to 8 and 11 to 22 survive termination. Termination does not entitle you to a refund except as Apple or mandatory law provides.

18. Changes to these terms

We may update these Terms from time to time. We will change the effective date above and, for material changes, tell you in the app or on this website before they take effect. Continuing to use Stowbook after changes take effect means you accept them. If you do not agree, stop using the app and cancel any subscription.

19. Governing law and disputes

These Terms and any dispute arising out of or relating to them or to Stowbook are governed by the laws of the jurisdiction where the developer resides, without regard to conflict-of-law rules, and the courts of that jurisdiction have jurisdiction, except where mandatory consumer law of the country where you live says otherwise. If you are a consumer in the European Union, the United Kingdom, Australia or another country whose law gives you the right to rely on its mandatory consumer protections or to bring proceedings in your local courts, nothing in these Terms takes those rights away. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Before starting any proceeding, please contact us so we can try to resolve the issue informally. To the extent permitted by law, any claim must be brought within one year after it arises, or it is permanently barred.

20. Apple App Store terms

If you downloaded Stowbook from the Apple App Store, you and we acknowledge that:

• These Terms are between you and the developer only, not with Apple Inc. (“Apple”). The developer, not Apple, is solely responsible for Stowbook and its content.
• The license granted to you is limited to a non-transferable license to use Stowbook on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that it may be accessed and used by other accounts associated with you via Family Sharing or volume purchasing.
• The developer is solely responsible for providing any maintenance and support for Stowbook as specified in these Terms or as required by applicable law. Apple has no obligation whatsoever to furnish any maintenance and support services with respect to Stowbook.
• The developer is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of Stowbook to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any, for the app to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to Stowbook, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty will be the developer’s sole responsibility, subject to these Terms.
• The developer, not Apple, is responsible for addressing any claims by you or any third party relating to Stowbook 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, including in connection with the app’s use of the HealthKit and HomeKit frameworks, if any.
• In the event of any third-party claim that Stowbook or your possession and use of it infringes that third party’s intellectual property rights, the developer, not Apple, will be solely responsible for the investigation, defense, settlement and discharge of any such intellectual property infringement claim, subject to these Terms.
• You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been 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.
• You must comply with applicable third-party terms of agreement when using Stowbook, such as your wireless data service agreement.
• Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
• Questions, complaints or claims about Stowbook should be directed to the developer at the contact details in section 22.

21. General

Entire agreement. These Terms, together with the Privacy Policy and, where applicable, Apple’s Standard EULA, are the entire agreement between you and us about Stowbook and replace any prior understandings. Severability. If any provision is held invalid or unenforceable, it will be enforced to the maximum extent permissible and the rest of these Terms remain in full effect. No waiver. Our failure to enforce a provision is not a waiver. Assignment. You may not assign these Terms without our consent; we may assign them to a successor to the app. Force majeure. We are not liable for delays or failures caused by events beyond our reasonable control, including failures of third-party services. Interpretation. Headings are for convenience only, and “including” means “including without limitation”. Language. These Terms are written in English; any translation is for convenience, and the English version governs where permitted by law.
