This policy is for purchases from Zypher Systems, LLC (“Zypher,” “we,” “us”). It covers hosted products we operate (including Mnemo), consulting engagements, and any paid digital goods we list on the pricing page.
Product marketing sites and apps — for example meetmnemo.com — do not change who you bought from. If checkout happens on a product domain, the seller is still Zypher Systems, LLC. Read this with the Terms of Use.
If a consumer-protection law where you live gives you a stronger right, that right still applies.
Free plans and free software
Mnemo Free, the public n8n workflow templates, and the in-browser developer tools do not cost money. There is nothing to refund. Closing a Free workspace or unused account is not a refund request.
Hosted subscriptions
This section applies to Mnemo Pro and any other paid hosted plan we list.
- You can cancel a paid plan so it does not renew. Cancellation stops the next charge; it does not by itself refund time already paid.
- The first successful charge for a paid plan is refundable if you ask within fourteen (14) days of that charge and the account has not been closed for a Terms violation.
- Later renewal charges are generally not refunded for unused days, unused storage, or unused API or MCP calls, unless we cancel the product or the law requires it.
- If we permanently shut down a paid product and you have prepaid unused time, we will refund the unused portion.
- We may refuse a refund if the account was used to break the law or the Terms, or if the request is fraudulent.
Taxes collected on a charge are refunded with that charge when we issue the refund.
Consulting
Consulting is quoted in writing before any money moves. The written agreement controls deposits, milestones, and what happens if the work stops.
- If we have not started the scoped work, we will refund a deposit you already paid.
- If work has started, we bill for work delivered under the agreement. We do not refund completed milestones.
- If we cannot deliver the agreed scope, we refund the unused paid amount for work we did not deliver.
Starting prices on Pricing and Services are estimates, not a purchase.
Paid digital downloads
We do not currently sell paid downloads. If we list one later, a refund is available before you download the files, or if the file we delivered is defective and we cannot replace it. After a successful download of a working file, sales are generally final unless the law requires otherwise.
How to ask
Email zypher@zyphersystems.com. For a Mnemo charge you can also write support@meetmnemo.com.
Include:
- The email on the account or invoice
- What you bought, and the approximate date
- The last four digits of the card, or the processor receipt, if you have it
- Why you are asking
We will reply within a few business days. Approved refunds go back to the original payment method. The processor and your bank decide when the credit lands — often several business days, sometimes longer.
Chargebacks
Ask us first. A chargeback for a charge we would have refunded under this policy wastes everyone’s time and can freeze the account while the processor investigates. We will still respond to a dispute with the records we have.
Changes
We may update this policy. The “Last updated” date at the top will change. The policy in effect on the date of a charge applies to that charge, except where the law requires something else.
