About

The studio behind Tendor

Tendor is built by Datadir, a small independent software studio. We make focused Shopify apps that do one job well — and let you undo anything.

What we build

Tendor is a suite of focused Shopify apps — back-in-stock alerts, pre-orders, scheduled sales, wishlists, SEO & link health, and more. Each one does a single job well instead of bundling a dozen half-features. Two principles run through all of them:

  • Reversible. Every change an app makes — a hidden product, a sale price, a pre-order toggle — records the exact prior state first, so it can be restored to the cent. Nothing is a one-way door.
  • Audited. Actions are logged, so you can always see what the app did and when.

How we work

We run these apps on real Shopify stores and test every release end to end — install, storefront, billing, and uninstall — before it ships. The guides in our content hub come from that hands-on work: they describe what Shopify actually does (and doesn't do) natively, then show where an app genuinely helps. We'd rather state a limitation plainly than overclaim.

Independent and EU-based

Datadir is a small, independent studio based in the EU — no venture backing and no sprawling roadmap, just a focused set of apps we maintain directly. When you email us, a person who actually works on the apps answers.
