Cancellation service #1 in Canada
Sidekiq is a background job processing tool for Ruby applications that moves work off web request threads into asynchronous workers. The open‑source Sidekiq gem provides core job processing; commercial Sidekiq Pro and Sidekiq Enterprise add reliability, monitoring, and enterprise features sold directly by Contributed Systems LLC.
When you cancel a Sidekiq Pro or Enterprise subscription, automatic renewal stops at the end of the current billing term unless the cancellation is combined with an approved refund that takes effect immediately. Your access to commercial features depends on the licensing terms - typically access continues until the paid term expires unless a refund is issued, in which case the subscription is cancelled immediately.
Contributed Systems maintains license records; you should keep invoices and license keys if you may re‑activate later. If you cancelled by postal mail, allow time for processing and confirm via the support email to avoid unintended renewal.
Sidekiq Pro and Enterprise offer refunds up to 14 days (two weeks) after purchase. To request a refund, email [email protected] with your reason and purchase details. If a refund is approved and issued, the subscription is cancelled immediately.
Because Sidekiq is sold by a U.S. company (Contributed Systems LLC), local Canadian statutory remedies may differ; if you have difficulties obtaining a refund, you may consider contacting your credit‑card issuer for dispute options. Always include purchase evidence when requesting refunds to speed resolution.

Under Canadian consumer protection practices, digital subscription products commonly offer a 14‑day cancellation/refund window, but specific statutory rights depend on how the product is delivered and on cross‑border purchase rules. Because Sidekiq is sold by a U.S. company, Canadian provincial consumer protection statutes may not automatically govern the contract; however, standard payment dispute channels (for example, contacting your card issuer) remain available if you cannot resolve a refund with the vendor.
Sidekiq’s stated 14‑day refund policy aligns with common industry practice for digital goods. Note that App Store or Google Play policies do not apply here because Sidekiq Pro and Enterprise are not distributed through those platforms.
Many users praise Sidekiq Pro for reliability, the dashboard and monitoring tools, and straightforward setup - feedback consistently highlights the operational stability Pro adds on top of the open‑source core. These strengths make it attractive for production workloads where background job reliability matters.
Some customers report downsides: at least one user said they were not notified before a license expired, which disrupted feature releases; others have expressed concerns about persistence and felt certain promised improvements were incomplete. These mixed reports suggest confirming license expiry dates and backup/monitoring practices before relying on any single support expectation.
Common mistakes include assuming app‑store cancellation processes apply - Sidekiq is not sold through App Store or Google Play, so attempting to cancel there will not stop Sidekiq billing. Another frequent error is failing to supply clear purchase evidence (invoice, license key, account email) when requesting cancellation or refund, which delays processing.
For postal cancellations, people often use untracked mail; because the vendor requires clear receipt, always use tracked, signed‑for shipping and then confirm via the support email to ensure timely handling.
| Method | Refund | Difficulty |
|---|---|---|
| Email to [email protected] | Possible within 14 days; refunds processed on request | Low |
| Postal tracked letter to PO Box (formal notice) | Possible within 14 days if refund requested via support; useful as formal record | Medium (slower processing) |
| Upgrade from Pro to Enterprise | Proration/cancellation of Pro applied if requested after purchase | Low |
| App Store / Google Play | N/A - Sidekiq is not distributed via app stores | N/A |
After you cancel, keep copies of the cancellation confirmation and any refund correspondence. If you need to follow up, email [email protected] (use [email protected]) and reference your original request, invoice number, and any tracking or confirmation numbers. For technical documentation, community support, and source code, see the Sidekiq repository and docs on GitHub: Sidekiq on GitHub.
For postal cancellation or formal billing notices, send tracked mail to:
Contributed Systems LLC, PO Box 247, Lake Oswego, OR 97034, United States
Use a tracked, signed‑for service (e.g., raccomandata A/R or equivalent) and keep the tracking/receipt number for your records.
