Frequently Asked Questions<br>How does docpenny compare to DocRaptor or PDFShift?<br>Unlike subscription-based services with expiring<br>credits, docpenny uses a pay-per-document model where<br>purchased credits never expire. You only pay for what<br>you actually use — no "use it or lose it" monthly<br>allowances.

What is the Free Tier?<br>Every account receives 50 free credits each month<br>(approximately 250 MB of rendered PDF output). This<br>allowance refreshes monthly and is always free — no<br>credit card required. Use it for testing, small<br>projects, or as a permanent free tier.

Is my data secure?<br>Yes. All data is encrypted at rest, and we automatically<br>purge all input data within 24-72 hours of job<br>completion. We process your data — we don't warehouse<br>it.

What template engines are supported?<br>docpenny supports raw HTML and CSS for full control over<br>your document layout, plus the Liquid template engine<br>for dynamic data binding. You can use any combination of<br>HTML, CSS, and Liquid in your templates.
