Last updated: 25 May 2026. We want you to love Drop Sigma. If it doesn't work for your business, here's exactly how cancellations and refunds work — no fine print, no surprises.
Every paid plan is covered by a 30-day money-back guarantee on your first paid month. Connect your store, run your real workflows for up to a month, and if Drop Sigma isn't a fit we'll refund the full amount.
To request it, email support@dropsigma.com within 30 days of your first paid charge and we'll process the refund.
You can cancel at any time from your dashboard:
After cancellation, you can re-subscribe anytime. Your data is kept for 90 days; after that it's permanently deleted unless you request export beforehand.
Outside of the 30-day window, we don't issue prorated refunds for unused time in a billing period. However:
If a payment fails (expired card, insufficient funds, etc.), we'll:
Please email us before initiating a chargeback — we will always work with you on a refund if you have a legitimate concern. Chargebacks cost us $25 in fees plus the disputed amount; merchants who initiate chargebacks without first contacting us forfeit any future refund eligibility.
Drop Sigma targets 99.9% uptime. If we drop below that in a calendar month, you receive automatic service credits on your next invoice — calculated as:
| Monthly uptime | Service credit |
|---|---|
| < 99.9% but ≥ 99.0% | 10% of monthly fee |
| < 99.0% but ≥ 95.0% | 25% of monthly fee |
| < 95.0% | 50% of monthly fee |
Credits are applied to your next invoice automatically — no action required.
If you installed Drop Sigma through the Shopify App Store, your billing is handled by Shopify (not us directly). Refund requests for App Store charges follow Shopify's refund flow:
Email support@dropsigma.com with:
We confirm receipt within 4 business hours and process refunds within 2 business days.
We may update this policy. Material changes (anything that shortens the refund window or reduces your protections) take effect 30 days after we email existing customers. Less impactful changes take effect immediately on this page.
Questions about billing or refunds: support@dropsigma.com — replies within 4 business hours.
