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 starts with a 14-day free trial. We do not ask for a credit card up front. If you decide not to upgrade, your account simply pauses at the end of the trial and your data is retained for 90 days in case you come back.
If you upgrade to a paid plan and aren't satisfied for any reason, email support@dropsigma.com within 30 days of your first paid charge and we'll refund the full amount.
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.
Plus customers with a 99.9% SLA receive automatic service credits for any month where uptime drops below 99.9%. Credits are 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:
