The main usage, purchase, and responsibility points for CNTC.
You are responsible for having permission or another lawful basis to share contact information.
No purchase is required to join, view, or edit a list shared with you.
Apple processes the optional purchase that unlocks unlimited list creation.
Sharing and synchronization depend on iCloud, CloudKit, and an active Apple Account.
These Terms govern CNTC, the CNTC website, shared-list collaboration, feedback services, and the optional Shared List Creator purchase. By using CNTC, you agree to these Terms. If you do not agree, do not use the app or website.
CNTC is distributed through Apple. Apple’s App Store terms and standard end-user license agreement also apply unless a different agreement is shown for CNTC. Apple processes App Store purchases, Family Sharing eligibility, purchase restoration, and refund requests.
CNTC is licensed, not sold. Subject to these Terms and Apple’s rules, you receive a limited, personal, non-transferable right to use CNTC on devices you own or control.
You may create or join lists for lawful purposes. Before sharing someone’s personal information, make sure you have their permission or another appropriate legal basis. Select only the fields participants need and review sensitive fields carefully.
You must not use CNTC to harass, impersonate, deceive, monitor, exploit, or harm another person; distribute unlawfully obtained information; bypass access controls; or violate privacy, data-protection, intellectual-property, or other laws.
Owners and authorized participants control list membership and permissions through Apple CloudKit. A participant may import or otherwise save information they can view. CNTC cannot guarantee that removing access deletes copies already saved outside the shared list.
If you create a CNTC invitation URL, you authorize CNTC to publish the list title and your short or customized invitation name to people who receive that URL. Choose a list title and invitation name suitable for disclosure, protect invitation URLs from unintended recipients, and disable or revoke links that should no longer be used. CloudKit remains the authority that grants or denies list access.
CNTC’s shared features depend on Apple Contacts, iCloud, CloudKit, compatible devices, network access, and an active Apple Account. Synchronization may be delayed or unavailable because of device state, account configuration, permissions, network conditions, Apple service availability, or software defects.
Review important information before relying on it. CNTC is not an emergency service, identity system, backup service, or guaranteed source of current contact information.
Joining, viewing, and editing a list shared with you does not require a CNTC purchase. The Shared List Creator product is a one-time in-app purchase that unlocks unlimited list creation for the Apple Account entitlement Apple reports to CNTC.
The price and currency shown by the App Store before confirmation apply. Apple controls payment, tax, Family Sharing, refunds, revocations, and transaction availability. If Apple revokes or refunds the entitlement, the unlocked creation capability may become unavailable. Existing CloudKit data is not intentionally deleted merely because an entitlement changes.
You may submit bug reports, feature requests, and other feedback. Do not submit confidential information, private contact data, invitation URLs, passwords, payment details, or unlawful content. You grant Altai permission to use feedback to operate, secure, and improve CNTC without an obligation to implement or compensate for it.
Do not attack, overload, probe, reverse engineer beyond rights granted by law, automate abusive requests, forge App Attest requests, or interfere with CNTC, its website, or other users.
We may improve, change, suspend, or discontinue features. We may restrict access to web services when reasonably necessary for security, abuse prevention, legal compliance, or service integrity. These actions do not give us access to delete private iCloud data we do not control.
We may update these Terms. Continued use after an updated version takes effect means you accept the revised Terms.
To the extent permitted by law, CNTC is provided “as is” and “as available.” We do not guarantee uninterrupted operation, error-free synchronization, participant behavior, or the accuracy of contact information. Nothing in these Terms excludes rights or remedies that cannot legally be excluded.
