Terms of service

The agreement between Projekt Studio and developers who hold a Passback account.

Last updated 12 October 2026.

1. Who we are

Passback is operated by Projekt Studio (“we”, “us”). Notices under these terms, and any question about them, go to info@projektstudio.com or through the contact page.

2. What Passback is

Two products, which you may use separately or together:

Web funnels. Building and hosting web funnels and paywalls for your app, taking payment through your own Stripe account, and telling your app who has paid.
Passback In-App. Checking your app's App Store and Google Play purchases on our servers, keeping a record of what each of your customers is entitled to, and telling your app, your server and your webhook endpoints.

We provide the software. You provide the app, the content, and the accounts with Stripe, Apple and Google that it connects to.

3. Your account

You must have the legal capacity to enter contracts in your jurisdiction, and you are responsible for activity under your account, including by anyone you give access to and by any API key or connected tool you create. One Stripe Connect account per Passback account. Tell us if you believe your account or a key has been compromised.

4. Fees

Web funnels are a flat monthly subscription, billed in advance through Stripe at the price shown on the pricing page when you subscribe: currently $250 a month for founding accounts and $500 a month at standard pricing. It includes Passback In-App.

Passback In-App on its own is free until your app makes real sales through the App Store or Google Play. Sandbox and TestFlight purchases never count. From then on it is a monthly price set by your tracked store revenue over the last thirty days, from $24 up to $149, as listed on the pricing page; when your revenue moves into a different tier, the new price applies from your next invoice. When your revenue first passes the free allowance we email you, and you have 14 days to subscribe; if you do not, Passback In-App stops answering for your apps until you do. Your data is kept meanwhile. Founding Passback In-App plans (the first 100, at $29 a month or $290 a year) are one price at any size.

A founding price is kept for as long as that subscription stays active without a lapse. We may change standard prices with thirty days' notice by email; a change never applies to a founding price. Prices exclude any tax that applies to you.

You may cancel at any time from the dashboard. Access continues to the end of the period you have paid for, and we do not refund partial periods, except where the law requires it or we have made an error in billing you.

We take no share of your customers' payments and charge no application fee.

5. Your customers, and who sells to them

On the web, charges are direct charges on your Stripe account and you are the merchant of record: you set prices, handle refunds and chargebacks, follow Stripe's terms, and answer to your customers and to tax authorities where you sell. Where you turn them on, Passback acts on your Stripe account for you: it creates checkout sessions, reads subscription state, cancels or refunds a subscription when your customer asks on the page we host for that and your refund policy allows it, and submits evidence to Stripe when a payment is disputed.

In the App Store and Google Play, Apple and Google sell to your customer under your agreements with them. Passback reads and records those purchases; it does not sell, refund or change them, and nothing in these terms changes your obligations to Apple or Google.

6. Access you give us

To work, Passback needs access to your accounts elsewhere: a Stripe Connect connection, and, if you use them, App Store Connect and In-App Purchase keys, a Google Play service account, and connections to ad networks. We use each one only to provide the features you have turned on, store each key encrypted, and never show it again after you save it. An App Store Connect key used for importing is used for that import and not stored. You can remove any of them at any time, and you should revoke them with Apple, Google or the network too if you stop using Passback.

7. Your responsibilities

Your funnel content must be accurate, lawful, and yours to use.
Your app must follow Apple's and Google's policies, including how it refers to web purchases.
You tell your customers about the data you collect and the emails they will receive, and you have a lawful basis for it. The privacy policy and data processing terms describe our part.
You will not use the service for anything unlawful, deceptive, or prohibited by Stripe, Apple or Google; try to reach other accounts' data; get around limits or billing; or load-test the service without asking us first.

8. Our responsibilities

We will run the service with reasonable care and skill, handle data as the privacy policy and data processing terms describe, and tell you about any security incident affecting your account without undue delay. We do not currently offer a contractual uptime commitment; current availability is on the status page. We make no promise about conversion rates or revenue. Features that draft content for you, such as a first funnel or a suggested screen, can be wrong; check what they produce before you publish it.

9. Ending the agreement

You may close your account at any time; subscriptions on your Stripe account keep billing, and store subscriptions stay with Apple and Google. We may suspend an account that breaches section 7, and will tell you why. If we stop offering the service we will give at least ninety days' notice and provide an export of your funnels, customer records and catalogue on request.

10. Liability

To the extent the law allows, the service is provided as is; we are not liable for lost revenue, lost customers, or indirect or consequential loss; and our total liability to you in any twelve months is limited to the fees you paid us in those twelve months. Nothing in these terms limits liability that the law does not allow to be limited.

11. General

These terms are governed by the law of the place where the operator of Passback is based, and disputes go to its courts, except where your local consumer law says otherwise. If any clause cannot be enforced, the rest still applies. We may update these terms; the date at the top changes, and we email account holders before a material change takes effect.
