Terms of Service

 App: Contacts: Caller ID & Blocker Effective date: September 3, 2026

The following Terms of Service ("Terms") form the agreement under which the Contacts: Caller ID & Blocker application (the "App") is made available to you by its developer ("we", "us", "our"). Downloading, installing, or using the App places you under these Terms. Where they are not acceptable, the App should not be used.

1. Description of the Service

The App manages contacts and controls incoming calls. It lets you organise and search the people in your list, place calls, review call history, see who is calling before answering, block numbers you do not wish to hear from, and filter suspected spam. Availability of individual features depends on the permissions you grant and on your handset — including whether the App has been made your default dialer.

2. Free Tier and Subscription

The App's core contact and call-control features are free to use, and the free tier is supported by advertising. Taking out a subscription does two things: it removes advertising, and it unlocks the App's pro features. The features covered by a subscription are identified inside the App, and that set may be extended or adjusted as the App develops.

3. Billing, Automatic Renewal, and Cancellation

Subscriptions are sold exclusively through the Google Play billing system, at the price shown to you before purchase is confirmed. A subscription renews automatically at the end of each billing period, the charge falling on your Google Play account under Google's terms, unless cancellation has taken place beforehand. Cancellation is carried out in the Play Store under "Subscriptions", after which the subscription continues to the end of the period already paid for and access is retained until then. Removing the App from your handset cancels nothing — only the Play Store can end a subscription.

4. Refunds

Refunds fall under the Google Play refund policy and are assessed and issued by Google rather than by us. Where a charge appears to have been made in error, you are welcome to contact us as well and we will assist to the extent we can, though the final determination on any Play Store refund belongs to Google.

5. Eligibility and Purchases Made by Minors

Use of the App is permitted from the age of 13, or from any higher minimum age fixed by the law where you are. A person aged between 13 and 18 requires the permission of a parent or legal guardian, who thereby accepts these Terms on that person's behalf.

A subscription or purchase made by a minor holds good only where a parent or legal guardian agreed to it in advance. An adult who permits a minor to use a handset signed in to the adult's Google Play account carries responsibility for the purchases made from it. Enabling purchase authentication in Google Play — requiring a password or fingerprint before every purchase — is the effective safeguard, and we recommend it on any handset a child can use. Where an unauthorised purchase has nonetheless occurred, the route to a refund runs through Google Play.

6. Acceptance and Subsequent Revision

Using the App constitutes acceptance of these Terms. Revisions may be made; the version currently in force, bearing its effective date, is always published on this page, and continued use after a revision constitutes acceptance of that revision. Where a revision does not suit you, ceasing to use the App is the available remedy.

7. Information Used by the App

Subject to the permissions you grant, the App works with contact records, call history, and associated device data so as to deliver caller identification, call history, blocking, and spam filtering. The detail is set out in our Privacy Policy, which forms part of these Terms. Personal data is not sold, and disclosure is confined to the providers identified in that policy.

8. Obligations When Using the App

The App is to be used for lawful purposes only. Responsibility for the manner in which its calling, blocking, and reporting features are used — compliance with the law of your jurisdiction included — rests with you, as does the accuracy of the contact information you maintain. The App must not be employed to harass any person, to submit false spam reports, to interfere with emergency communications, to circumvent the subscription, or to obtain unauthorised access to connected systems. Under no circumstances should the App serve as your sole means of contacting emergency services; your handset's native emergency calling must remain available at all times.

9. Controls at Your Disposal

Permissions may be withdrawn through Android settings; contacts may be amended or deleted; call history may be cleared; blocked numbers may be released; the default dialer may be changed; and the App may be uninstalled — each at any time and entirely at your discretion.

10. Ownership and Licence

Code, design, graphics, and other materials originating with us are our property and enjoy the protection of intellectual property law. What is granted to you is a limited, personal, non-exclusive, non-transferable licence to use the App, together with any pro features your subscription unlocks, for private and non-commercial purposes. Reproduction, alteration, redistribution, sale, and reverse engineering are not permitted absent our written consent. Contacts and other content of your own remain yours throughout.

11. Advertising

Where no subscription is running, advertising is displayed through third-party networks such as Google AdMob. Any dealings arising between you and an advertiser are exclusively between the two of you; we accept no responsibility for the content of third-party advertising or for the goods and services promoted through it. Advertising ceases while a subscription is active.

12. Disclosure

Information may be disclosed where the law so requires, or where disclosure is reasonably necessary to prevent fraud or abuse, to protect the rights and safety of users, or to enforce these Terms.

13. Termination

You may bring your use of the App to an end at any time by uninstalling it — noting that a subscription survives uninstallation and must be cancelled separately through the Play Store. Access may be suspended or terminated by us without prior notice where these Terms are breached, where the law obliges us, or where continued provision of the App would expose us to legal or operational risk. Provisions which by their nature ought to survive termination — ownership, disclaimers, limits on liability — continue in effect.

14. Absence of Warranty

The App is furnished "as is" and "as available", without warranty of any description, express or implied. No promise is made that operation will be uninterrupted or free of error, that every unwanted or spam call will be intercepted, that caller identification will invariably prove accurate, or that defects will be remedied.

15. Limitation of Liability

To the fullest extent permitted by law, no liability attaches to us for indirect, incidental, special, consequential, or punitive damages — including missed or failed calls, loss of data, loss of contacts, loss of profit, and device malfunction — arising from use of the App or from any inability to use it, even where the possibility of such damage had been drawn to our attention.

16. Disputes

Contact us first at the address below; the overwhelming majority of matters are resolved that way. Where informal resolution fails, the dispute is to be determined under applicable law by the competent courts of the place in which the defendant is located, save where mandatory law directs otherwise.

17. General Provisions

Should any provision of these Terms be held invalid or unenforceable, the remainder continues in full force. A decision not to enforce a provision on a given occasion operates as no waiver of it.
