Data deletion

If you signed up for a ChatLedger workspace (you're a Casia Lab Customer), the fastest way to delete everything is from the product:

1. Sign in at chatledger.casialab.com.
2. Open Settings → Danger zone.
3. Click Export my data first if you want a copy (recommended — we can't recover it once it's deleted).
4. Click Delete workspace, type your workspace name to confirm, and submit.

You can cancel the request at any point during the 30-day grace window from the same screen. After 30 days, deletion becomes permanent and the workspace cannot be restored.

If you can't access the product — or you're an End User (someone who messaged a business using ChatLedger) — write to chatledger@casialab.com with the following:

• Your name and phone number or email address as we'd have it on file.
• For End Users: the business name or WhatsApp number you were messaging. We can only identify your data through them.
• (Optional) A short reason — helps us serve you better, but you're not required to share one.

We confirm receipt within 2 business days and complete the deletion within 30 days of confirmed identification, in line with applicable data protection laws (including GDPR, UK GDPR, NDPA, UAE PDPL, and equivalent regimes).

When a workspace is purged, we cascade-delete every row tied to it:

• Tenant profile — business name, address, currency, settings.
• Staff accounts — names, roles, contact details.
• Customers — phone numbers, names, tags, notes, history.
• Conversations and every message in them, including media references.
• Quotes, orders, payments, delivery records.
• AI Support runs and credit ledger entries.
• Payment method configuration (Stripe / Paystack / bank details).
• Auto-reply, business-hours, and AI knowledge configuration.

For End Users requesting deletion, we remove the customer record and all linked conversations, messages, orders, and payments from the businesses you specified — without affecting other people in those businesses' data.

Tax, accounting, and anti-fraud laws in the jurisdictions we and our Customers operate in require us to retain certain financial records. Specifically:

• Tax-relevant invoices and payment records — 5–10 years depending on the jurisdiction (e.g. 7 years under Nigerian Federal Inland Revenue Service rules, 10 years under UK HMRC, 6 years under typical EU member-state regimes).
• Encrypted backups — overwritten on a rolling 35-day cycle. Your data will be removed from the next backup generation onward.
• Sub-processor logs — message delivery records held by Meta (WhatsApp) follow Meta's own retention policy. We don't control those directly. Contact Meta if you need those purged.

• Day 0 — you submit the request (in-app or by email).
• Days 0-30 — grace window. The workspace stays accessible but flagged for deletion. You can cancel.
• Day 30 — the workspace is hard-deleted from our primary database.
• Day 65 (≈) — the data also drops out of our rolling backups.
• 5–10 years — invoices and payment records retained for tax compliance, depending on the jurisdiction.

Write to chatledger@casialab.com and we'll walk you through it. If you believe your data has been mishandled, you can also complain to your local data protection authority — see the "Complaints" section of our privacy policy for the appropriate regulator in your region (EU/EEA national authorities, UK ICO, Nigeria NDPC, UAE Data Office, etc.).
