When file protection isn't the full job.
LDT's strongest angle is file protection — PDF and EPUB watermarking, password encryption, adaptive streaming with subtitles. For a publisher selling ebooks or a creator selling video courses, those are real features. But digital fulfilment on Shopify is a wider problem than "lock the file." Four concrete reasons merchants move from LDT to Alva:
Alva scores every paid order against 40+ fraud signals via Shopify's Risk API before the download URL is released. License keys are only assigned after approval. Fraud detection is not a headline feature of the LDT listing — a single chargeback on a $40 course typically costs more than a year of Alva's Basic plan.
Alva auto-generates license keys per order or bulk-imports an existing pool, assigns only after fraud approval, revokes and reissues on refund, and sends low-stock alerts. Keys never ship to a high-risk order — which matters when your key pool has real per-unit cost.
LDT delivers via email and a customer portal. Alva places the download link in four places: the branded email, the thank-you page, the Shopify order status page, and the Shopify customer account portal. If any one channel is delayed or lost, the other three are live.
Alva supports Shopify POS for in-store sales of digital goods, bundles (auto-attach every nested file), subscriptions (fresh signed link each renewal) and a full made-to-order production workflow. POS is not a headline feature of the LDT listing, so merchants selling digitally at events or in-store typically have to bolt on a second app.
Three differentiators, in detail.
Fraud protection and license-key flow
LDT, like most digital-download apps focused on file protection, is not a fraud-prevention platform. Watermarks and encryption stop the file being redistributed after delivery — they don't stop the delivery being triggered by a stolen card in the first place. That's the core risk on high-AOV digital goods: software, courses, professional PDFs, commercial licences. Once the license key is emitted to a stolen-card order, Shopify can reverse the transaction but the key has already been used.
Alva sits the license-key machine on top of the fraud layer. Every order runs through Shopify's Risk API with 40+ signals — AVS mismatch, VPN and proxy detection, device fingerprint, chargeback history, email age, CVV. High-risk orders hold pre-delivery, keys stay unassigned until approval, and the full approve/reject audit trail is captured. On low-inventory key pools, pending assignments queue until refill. Across Alva's merchant base the false-positive rate is 0.4%.

The delivery surface — four channels, not two
LDT delivers via email and a branded customer portal. That's two channels: an outbound message and a persistent dashboard. It covers the base case. It doesn't cover the awkward middle — the customer who completed checkout, is staring at the thank-you page, wants the file now, and doesn't know (or can't be bothered) to log into a portal.
Alva adds two more channels for that exact moment. The thank-you page (via Shopify's Checkout UI Extensions) shows the download link immediately after payment using a provisional-download token. The Shopify order status page (the confirmation page customers bookmark) shows the same link, refreshed. The customer account portal (Shopify's native one) lists all purchases across orders. Combined with the email, that's four live paths. If any channel fails or is delayed, the customer always has at least one working link.
- Postmark-backed · your domain on every paid plan
- Thank-you page
- Provisional download token · instant
- Order status
- Shopify order status extension
- Customer account
- All purchases in one list
Feature coverage — POS, bundles, made-to-order, Flow
LDT's strongest investments are file protection (PDF/EPUB watermarking, encryption) and media playback (adaptive video/audio streaming with subtitles). Those are well-suited to a publisher or course creator. Alva's feature surface is oriented differently — toward the operational edges of Shopify digital fulfilment.
Alva supports Shopify POS for in-store digital sales. Bundles auto-attach every nested file. Subscriptions reissue a fresh signed link on each renewal. 14 Shopify Flow actions and triggers automate resend, grant access, revoke access, approve/reject high-risk orders. Made-to-order work — wedding invitations, custom portraits, photo edits, logo design — has a built-in production workflow: brief at checkout, admin tracking, upload the final file, Alva delivers automatically.
