Refund Policy
Last updated September 19, 2026.
We offer refunds for unresolved technical problems, plus any refunds required by law. For help with your purchase, email [email protected].
When a refund is available
If a technical problem prevents marginstudy from working as described on a supported Mac and we cannot reasonably resolve it, we will provide a refund. This includes persistent problems that prevent you from accessing the advertised features you purchased.
We do not offer change-of-mind refunds simply because you no longer need the app or prefer a different workflow, unless applicable law or the seller’s terms give you that right. The direct-download app includes a 14-day trial so you can try it with your own PDFs before purchasing.
How to request help or a refund
Email [email protected] with your order reference or purchase email address, a description of the problem, and your Mac model, macOS version, and marginstudy version. This helps us find your purchase and understand the issue.
We may ask for reasonable troubleshooting details or suggest a fix. You do not need to send payment card details, your full license key, or private textbook or note content. Troubleshooting will not restrict or delay a refund or other remedy you are entitled to by law.
Your local notes and backups
Your notes and study workspace are stored locally on your Mac. We can help troubleshoot the app, but we cannot access your locally stored notes or restore them from our systems if your files are deleted or corrupted. We do not keep server copies. Keep backups of your PDFs and workspace; recovery depends on a usable backup or local recovery copy that you control.
This storage limitation does not change your eligibility for a refund for an unresolved technical problem or any remedy required by law.
Who processes the refund
Lemon Squeezy processes refunds as the merchant of record for purchases through this website. Email us using the details above so we can review your request and arrange an eligible refund through Lemon Squeezy.
Lemon Squeezy’s Buyer Terms also apply. Lemon Squeezy may approve refunds under its own policies; this page does not limit those rights. Approved refunds are generally returned to the original payment method. Processing and bank posting times vary.
After a refund, the corresponding paid license may be deactivated. A refund does not delete files stored locally on your Mac.
Your consumer rights
Nothing in this policy limits mandatory consumer rights, including rights relating to faulty, misdescribed, or undelivered digital products and any applicable cancellation or withdrawal rights. If local law gives you a stronger remedy or a different time limit, that law applies.
Using or downloading marginstudy does not, by itself, waive rights that cannot lawfully be waived. Any legally valid waiver of a withdrawal right must meet the requirements of the law that applies to your purchase.
About this policy
This policy covers purchases of marginstudy, developed and operated by Alric Siu. The policy in effect when you purchase applies to that purchase, together with your statutory rights and the seller’s terms. Our Terms of Service explain the app license.
