Privacy Policy

Last updated: November 11, 2026

Availify Filter (the “App”) is a Shopify app made by Nitro Studio (“we”, “us”). This policy explains what information the App processes when a merchant installs it and when shoppers visit a store that uses it. In short: the App does not collect personal information about shoppers, and it keeps only what Shopify requires for the merchant’s installation to work.

1. Information we collect from merchants

When you install the App, Shopify shares with us the information needed to connect your store. We store:

  • your store’s myshopify.com domain;
  • the access token and refresh token Shopify issues for the installation, with their expiry dates;
  • the permissions (access scopes) granted to the App.

The App requests no Admin API access scopes. It does not read your products, orders, customers, inventory or other store data through Shopify’s APIs, and it does not ask for or store the name or email address of you or your staff.

If you email us for support, we also receive your email address and the content of your message.

2. Information about shoppers

On your storefront, the App runs as a theme app embed. When a shopper uses a filter on a collection or search page, a small script in their browser adds your store’s In stock filter to the request. This all happens inside the shopper’s browser:

  • The App does not collect, receive or store any personal information about shoppers, and it sends nothing to our servers.
  • The App does not set cookies and does not track shoppers.
  • To remember a shopper’s own choice about the In stock filter during their visit, the script saves two small values in the browser’s session storage (availifyFilter.optOut and availifyFilter.reconciled). They contain no personal information, never leave the shopper’s device, and are deleted by the browser when the tab is closed.

Because of this, the App has no customer data to report or delete in response to Shopify’s customer data request and customer redaction webhooks.

3. How we use information

  • to install, authenticate and run the App on your store;
  • to respond to support requests;
  • to keep the App secure, prevent abuse and meet legal obligations.

We do not sell personal information, we do not share it for cross-context behavioral advertising, and we do not use it for marketing profiles.

4. Legal bases (EEA, UK and Switzerland)

Where the GDPR or UK GDPR applies, we process merchant installation data to perform our contract with you (providing the App), and we process server logs and support emails on the basis of our legitimate interest in operating a secure, supported service. For shopper-facing storefront features, the merchant is the controller of their store and we do not process shopper personal data.

5. Sharing and service providers

We share information only with:

  • Shopify, which provides the platform the App runs on;
  • our hosting provider, which runs the App’s servers and database;
  • our email provider, for support conversations;
  • authorities or other parties when the law requires it, or to protect our rights, users or the public.

6. Retention and deletion

  • When you uninstall the App, Shopify notifies us and we delete your store’s installation record, including its access tokens.
  • Shopify sends a store redaction request 48 hours after uninstall; we then delete any remaining data held for your store.
  • Server logs, which can include IP addresses and request details, are kept for a limited period, normally no more than 30 days, unless needed to investigate a security issue.
  • Support emails are kept as long as needed to resolve your request and for a reasonable period afterwards for our records.

7. Security

All connections to the App use HTTPS. Shopify verifies requests to the App, and we verify the signature of every webhook Shopify sends. Access to our servers and database is restricted. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

8. Your rights

Depending on where you live, you may have the right to access, correct, delete or export your personal information, to object to or restrict certain processing, and to complain to your local data protection authority. California residents have the right to know, delete and correct personal information and not to be discriminated against for exercising these rights. Email us to make a request; we will respond within the time required by law. Shoppers with questions about a store’s data practices should contact that store directly.

9. International transfers

Our service providers may process information in countries other than yours. Where required, we rely on appropriate safeguards such as standard contractual clauses.

10. Children

The App is a business tool for Shopify merchants and is not directed to children under 16.

11. Changes to this policy

If we change what the App collects or how we use it, we will update this policy and the date above before the change takes effect. For significant changes we will also let merchants know by email or in the App.
