Operational gate. The periods below are publication targets. Engineering must verify active-database expiry jobs, object-storage lifecycle rules, backup expiry and legal-hold overrides before this notice is published.

1. Retention schedule

Data class	Default target	Reason / exception
Account/profile and number assignment	Account lifetime; deletion workflow normally completed within 30 days	Fraud, appeal, recovery and legal-hold exceptions
Messages and attachments	Until user/conversation deletion or configured retention expires	Recipient copies, reports, channels, backups and preservation may differ
Call signalling and quality metadata	12 months	Shorter geo policy or longer dispute/legal hold
Call media	Not retained by default; authorised recordings until user deletion or configured expiry	Exported copies are controlled by the exporter
Precise shared location	Same as the message or live-share duration	Security report or lawful preservation
IP, login, device and session security logs	12 months after event or device removal	Longer for substantiated abuse, ban evasion or law
Support tickets and ordinary appeals	24 months after closure	Legal dispute or regulator request
Moderation reports and decisions	24 months; up to 5 years for serious/repeated safety abuse	Proportional evidence and repeat-infringer duties
KalCoin ledger, purchases, refunds and accounting	7 years or the locally required tax/accounting period	Public blockchain records cannot be deleted by Kaltiq
Admin/audit and legal-request logs	7 years unless local policy requires less or more	Integrity, accountability and legal defence
Encrypted backups	Rolling expiry targeted within 90 days	Restored data is re-subjected to deletion queues

2. Account deletion

After verification, Kaltiq disables sign-in, revokes active sessions and begins deletion or de-identification. Identifiers may enter quarantine before returning to the pool. Outstanding disputes, negative/fraud adjustments and legally retained ledger entries remain restricted. Content already delivered to another user or made public is not automatically removed from their account or copies.

3. Message deletion

“Delete for me” hides a message from the requester but may leave it available to others. “Delete for everyone” requests removal of active copies Kaltiq controls, subject to time limits, moderation evidence, recipient exports and law. Tombstones may remain briefly to synchronise deletion across devices.

4. Legal holds and preservation

A valid preservation demand, litigation hold, safety emergency, payment dispute or regulator instruction pauses deletion only for relevant data. Held information is access-restricted, documented and deleted after the hold and any required defence period end.

5. Country policies

The compliance engine may apply a shorter country/data-class schedule. A longer period is used only when supported by a documented legal obligation or necessity. The effective rule is the shortest applicable period unless law requires preservation.

6. Requests

Request deletion or an explanation from the privacy/DPO contact at admin@kaltiq.com. We may verify identity and explain lawful exceptions. Appeals: appeals@kaltiq.com.
