Terms of sale and use
What you are buying when you buy a StratumCode app, how payment and delivery work, and what each of us can expect. Last updated 10 November 2026.
Who you are dealing with
StratumCode apps and this website are run by Theo van Stratum, trading as StratumCode, in Manila, Philippines. In these terms, “I” means StratumCode and “you” means the person who buys or uses an app. You can reach me through the contact form or at support@stratumcode.net.
What you are buying
You are buying a licence to use an app, not the app itself. I keep the copyright in the app and in everything on this website. The licence is personal to you, non-exclusive and non-transferable. It lets you install and use the app on your own Macs, for your own work or business.
Each app's page says what the price covers. Nothing is promised that the page does not say. In particular, a licence does not by itself entitle you to future major versions.
Trying before you buy
The apps can be downloaded and used for a trial period before you buy. The length of the trial is stated on the app's page. The trial is there so that you can decide whether an app suits you before you pay.
Price and payment
Prices are one-off fees in US dollars, as shown on the app's page. Payment is taken by PayPal, on PayPal's own pages, and PayPal shows you the amount before you pay. If you pay from a PayPal balance in another currency, PayPal converts the amount and applies its own exchange rate and fees. I do not control those and I do not see your card or PayPal login details.
A purchase is complete when PayPal confirms the payment to me. You will see a confirmation page with an order number. Please keep it.
Delivery of your licence
I make each licence by hand and email it to the address on your PayPal account, quoting your order number. This is not instant, and I do not promise a delivery time, but I will not leave a paid order unanswered. If it has not arrived, look in your spam folder, then write to me with your order number.
A licence contains your email address. Please check that the address on your PayPal account is the one you want it made for. If it is not, tell me before the licence is made.
Refunds
Because every app can be tried first, I do not give refunds once a licence has been issued. If an app does not work as described and I cannot fix the problem, I will refund you. Nothing in these terms limits any right you have under the law that cannot be excluded.
If a payment is refunded, or reversed through PayPal, the licence made for it is withdrawn. The apps check a small public list of withdrawn licences about once a week, so a withdrawn licence stops working the next time an app checks.
How you may use a licence
- Do not share your licence, publish it, or resell or pass it on.
- Do not copy, alter or remove the licence checks in an app, or make a licence that I have not issued.
- Do not copy, resell or redistribute the app itself.
If you break these terms I may withdraw your licence. Where that happens other than for a refund or reversal, I will tell you why.
Support
I support the apps I sell. Use the support form or write to support@stratumcode.net. I reply as soon as I can, but I do not promise a response time.
Your files and backups
Some apps change, move or delete files and data, which is what they are for. Keep backups of anything you care about before you use them, as you should with any software that works on your files. Each app says what it will and will not touch.
Limits on what I am responsible for
I build the apps with care and describe them honestly, but software can have faults and I cannot promise that an app will be free of them or suit every purpose. To the extent the law allows, the apps are provided as they are, I am not liable for loss of data, profit or business, or for indirect loss, and my total liability to you for any app is limited to the price you paid for it. This does not exclude or limit liability that the law does not allow to be excluded or limited.
Your personal information
What this website and the apps store and send is set out in the privacy notice.
Changes to these terms
If these terms change, the date at the top will change with it. The terms in force on the day you bought an app are the ones that apply to that purchase.
Governing law
These terms are governed by the laws of the Republic of the Philippines.
