Terms of Use

Caller ID (“the app”) · Last updated: 15 August 2026

These Terms of Use (“Terms”) are an agreement between you and Yoto Kimura (“we”, “us”) governing your use of the Caller ID iOS application. By downloading, installing or using the app you accept these Terms. If you do not accept them, do not use the app.

Read this if you read nothing else. Caller ID identifies numbers from published numbering-plan data stored inside the app. It tells you where a number range is registered and which operator it was originally allocated to — not who owns the phone, not where the phone is, and not, after number portability, necessarily which network it is on today. Spam verdicts are heuristics. Never rely on the app for an emergency, a legal, financial or safety decision.

1. Who may use the app

You must be at least 13 years old, or the minimum age of digital consent in your country if that is higher, and legally able to enter into this agreement. If you use the app on behalf of an organisation, you confirm you are authorised to accept these Terms for it.

2. Licence

We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use one copy of the app on Apple-branded devices that you own or control, as permitted by the App Store Terms of Service. You may not:

• copy, sell, rent, sublicense or redistribute the app;
• reverse engineer, decompile or disassemble it, or extract, scrape or republish its number database, except where such restriction is prohibited by law;
• remove or alter any notice of ownership;
• interfere with the app, its advertising, or any service it connects to, or use automated means to operate it.

The app, its design, its content and its compiled data remain our property or that of our licensors. Numbering-plan information is derived from published sources and used only as reference material.

3. Acceptable use

You agree to use Caller ID lawfully, and specifically not to use it to harass, stalk, threaten, defraud or intimidate anyone, to identify or profile a person without a lawful basis, to violate any telecommunications, anti-spam or data protection law that applies to you, or to build or feed a directory, database or service of your own. Caller ID is a tool for screening calls to your own phone, not an investigative or people-search service.

4. Accuracy — what the app can and cannot tell you

• Registration, not location. The map and place names show where a number range is registered by its numbering authority. They do not show where a phone or a person is.
• Original allocation, not current operator. An operator name reflects the network a number series was allocated to. Number portability means the current network can differ, and the app says so on screen.
• Heuristic verdicts. A “spam” or “safe” verdict comes from your own reports and blocks, whether the number is saved in your contacts, whether it falls in a known nuisance range, and the shape of the number itself. Legitimate callers can be flagged, and nuisance callers can go unflagged.
• No identity lookup. The app does not and cannot tell you the name of a stranger. Names come only from your own address book.
• No emergency use. Emergency numbers shown for reference must be verified locally. Never depend on the app to place, receive or screen an emergency call.

Data is provided “as is” and may be incomplete or out of date. You are responsible for how you act on it.

5. Call blocking on iOS

An app cannot intercept, screen or record calls on iOS. Caller ID hands your block list to iOS through a Call Directory extension; iOS decides what to block and identify. Blocking therefore requires that you enable the app under Settings → Apps → Phone → Call Blocking & Identification, and iOS may reload the list on its own schedule. Delays, partial loads and iOS limits on list size are outside our control, and we do not guarantee that any particular call will be blocked or identified.

6. Your contacts and your data

Contacts features require your permission and operate on the address book stored on your iPhone. Merging, editing and deleting contacts is permanent and cannot be undone from within the app. Use Back up to export a .vcf file, and keep your own backup (for example iCloud), before running a clean-up. You are solely responsible for your contact data and for any change you approve. All app data lives on your device; deleting the app deletes it, and we hold no copy that could be restored. How data is handled is described in our Privacy Policy, which forms part of these Terms.

7. Advertising

Caller ID is free and supported by advertising, including banner, native, interstitial and app-open ads served by Google AdMob and its mediation partners. Ads are not endorsements: we do not control advertisers and are not responsible for their products, claims, websites or practices. Interacting with an ad is a matter between you and the advertiser.

8. Purchases and subscriptions

The app may offer optional in-app purchases, including an ad-free upgrade, sold and billed by Apple through your App Store account. Where a purchase is a subscription:

• payment is charged to your App Store account at confirmation;
• it renews automatically for the same period unless auto-renew is turned off at least 24 hours before the end of the current period;
• renewal is charged within 24 hours before the period ends, at the then-current price;
• you can manage or cancel it in Settings → [your name] → Subscriptions; cancelling stops the next renewal and does not refund the current period;
• any free trial period not used is forfeited when a subscription is purchased.

Refunds are handled by Apple under the App Store Terms of Service; we cannot issue them. Prices may change, with any change applying only to future billing periods.

9. Notifications

With your permission the app sends reminders you create and occasional notifications about features and updates. You can turn these off at any time in iOS Settings without losing any other functionality.

10. Availability and changes

We may change, suspend or discontinue any part of the app, including features and the offline database, at any time. We aim to keep the app compatible with current iOS versions but do not guarantee support for older ones.

11. Disclaimer of warranties

THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED OR ERROR-FREE, THAT ANY NUMBER INFORMATION IS ACCURATE OR COMPLETE, OR THAT ANY CALL WILL BE BLOCKED OR CORRECTLY IDENTIFIED. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, CONTACTS, PROFITS, BUSINESS OR OPPORTUNITY, ARISING OUT OF OR RELATED TO YOUR USE OF THE APP — INCLUDING A MISSED CALL, A CALL WRONGLY BLOCKED OR WRONGLY ALLOWED, AN INCORRECT VERDICT, OR CONTACTS LOST THROUGH A MERGE OR DELETE YOU APPROVED. OUR TOTAL LIABILITY FOR ALL CLAIMS IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US FOR THE APP IN THE TWELVE MONTHS BEFORE THE CLAIM, OR USD 25.

13. Indemnity

You agree to indemnify and hold us harmless from any claim, damage or expense (including reasonable legal fees) arising from your misuse of the app or your breach of these Terms or of any law.

14. Apple

• These Terms are between you and us, not Apple. Apple is not responsible for the app or its content.
• Apple has no obligation to provide maintenance or support for the app.
• If the app fails to conform to any applicable warranty, you may notify Apple, which will refund the purchase price if any; to the maximum extent permitted by law, Apple has no other warranty obligation.
• Apple is not responsible for addressing any claim relating to the app, including product liability, legal or regulatory non-compliance, or consumer protection claims.
• Apple is not responsible for the investigation, defence, settlement or discharge of any third-party claim that the app infringes intellectual property rights.
• You confirm that you are not located in a country subject to a US Government embargo or designated as “terrorist supporting”, and that you are not on any US Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

15. Termination

These Terms apply for as long as you use the app. You may end them at any time by deleting the app. We may suspend or terminate your licence if you breach them. Sections 4, 6 and 11 to 16 survive termination.

16. Governing law and disputes

These Terms are governed by the laws of [COUNTRY / STATE], without regard to conflict-of-law rules, and the courts of [CITY, COUNTRY] have exclusive jurisdiction. Nothing here removes a mandatory consumer-protection right you have in your country of residence, including the right to bring proceedings there.

17. General

These Terms, together with the Privacy Policy, are the entire agreement between us about the app. If a provision is held unenforceable, the rest remains in force. Our failure to enforce a provision is not a waiver of it. You may not assign these Terms; we may assign them as part of a merger or sale of assets. We may update these Terms, and continued use after an update means acceptance; the “last updated” date shows the current version.
