Terms of Service

Last updated 5 September 2026

These terms are a contract between you and DifferApps ("DevPacs", "we", "us"). They cover the DevPacs mobile apps, the developer console at app.devpacs.com, and this website. By creating an account you accept them. If you don't, don't use DevPacs.

1. Eligibility and your account

You must be at least 16 years old to use DevPacs. You need one account, registered with a valid email address, and you are responsible for what happens under it. Don't share your login, and tell us promptly if you think someone else has access.

There is one kind of member. Pack roles are contextual, but during early access only developer-to-developer Duos are open: both members must bring a live app. Tester-only joins and seven-person Squads are not currently available.

2. How packs work

A Duo pairs two developers for a run lasting up to 24 hours after both install proofs are approved. Each member completes one task in the other's app. To complete it you must open the app through DevPacs, spend the minimum period using it, and submit a screenshot with a written response before the run closes.

The developer who owns an app reviews the submissions on it and approves or rejects each one. If your submission is rejected you may dispute it once, with a note. Disputes are resolved either by another member of the same pack or by an administrator, and the decision is final.

Inactivity points. Missing a Duo task adds 10 account-wide inactivity points; completing one removes 5, down to zero. At 20 points you cannot join a new Duo until the points are cleared. A failed Duo forfeits its entry fee and banked earnings.

3. Tokens

Tokens are a virtual, in-app currency used to join packs, post bonus tasks and export feedback, and are earned by completing tasks. New accounts receive a one-off grant of tokens.

You need to understand the following about tokens:

• Tokens have no monetary value, are not a currency, and are not your property.
• They cannot be exchanged for cash, redeemed, refunded, or transferred to another person.
• They are a limited, revocable, non-transferable licence to use a feature of DevPacs.
• Tokens earned during a pack are banked and become spendable only when that pack closes.
• We may change token prices and earning rates. We'll give notice in the app before a change to the rates takes effect.
• If your account is terminated for breaking these terms, any remaining tokens are forfeited.

4. Purchases and refunds

Token packs and inactivity-point clears are sold through Stripe Managed Payments on the web. Stripe, trading through Link, is the merchant of record and handles the payment details. Prices and applicable tax are shown before you confirm. DevPacs does not currently sell subscriptions.

If a purchase is duplicated, fraudulent, not delivered, or materially defective, email hello@devpacs.com with the account email and Stripe receipt. You may also request a refund through Link support. Stripe may issue refunds under its Managed Payments terms. When a purchase is refunded, the associated tokens or entitlement are removed from the DevPacs account. Nothing here limits statutory consumer rights.

5. The payment testing policy

6. Acceptable use

You agree not to:

• Submit fake, recycled, automated or AI-generated proof, or feedback you did not genuinely produce by using the app
• Reject valid submissions to avoid paying out, or approve submissions you know to be fake
• Create multiple accounts, or coordinate with others to manipulate packs, tokens or disputes
• Harass, abuse, threaten or discriminate against another member
• Post illegal, infringing, malicious or sexually explicit content
• Attempt to breach, probe or overload our systems, or to access data belonging to others
• Use DevPacs to distribute malware, phishing, or an app whose purpose is to deceive
• Submit false reports or abuse the dispute system

7. If you bring an app

You confirm, for every app you add, that:

• You own it or are authorised to submit it for testing
• It is available at the store link you provide, and that link is accurate and current
• It does not contain malware, and it complies with the rules of the store it is published on
• It does not require members to disclose sensitive personal data or make personal payments
• You will review submissions on your app promptly and in good faith

DevPacs does not vet or endorse the apps in a pack. Testing an app is at your own discretion and risk, and your relationship with that app's developer, including their own terms and privacy policy, is between you and them.

8. Your content and feedback

You keep ownership of the screenshots, responses and feedback you submit. You grant DevPacs a non-exclusive, worldwide, royalty-free licence to host, store, reproduce and display that content for the purpose of operating the platform.

You also grant the developer of the app you tested a perpetual, irrevocable, royalty-free licence to use your feedback on that app to improve it, including after your account closes. Feedback given in a pack is meant to be acted on; you cannot require a developer to un-read it.

Developers can export the feedback on their own app. Once exported, that copy is outside our control.

9. Enforcement

Reports about members and tasks are reviewed by an administrator, who decides whether to uphold them. An upheld report can result in a note on the account, a formal warning, removal from a pack, or a permanent ban. Banned email addresses are blocked from joining new packs. We aim to apply this proportionately, and we may act without prior notice where a breach is serious.

10. Ending your account

You can delete your account at any time from your profile settings. Deleting mid-pack forfeits your entry fee and any tokens banked in that pack.

We may suspend or terminate your account if you break these terms, if we're required to by law, or if we discontinue the service. If we discontinue DevPacs entirely we will give reasonable notice in the app.

11. Disclaimers

DevPacs is provided "as is" and "as available". We do not warrant that packs will fill, that every member will complete their tasks, that the feedback you receive will be useful or of any particular quality, or that the service will be uninterrupted or error-free. Nothing here excludes liability we cannot exclude by law, including for death or personal injury caused by negligence, or for fraud.

12. Limitation of liability

To the fullest extent permitted by law, we are not liable for indirect, incidental, special or consequential loss, or for lost profits, lost revenue, lost data, or loss of goodwill arising from your use of DevPacs. Our total liability to you in any twelve-month period is limited to the greater of the amount you actually paid us in that period, or £50.

If you are a consumer, you have legal rights that these terms do not affect, and nothing in this section limits them.

13. App store terms

You obtained the DevPacs app from Apple or Google. Those companies are not parties to these terms and have no responsibility for DevPacs. Apple and Google are, however, third-party beneficiaries of these terms and may enforce them against you. Your use of the app must also comply with the applicable app store's terms of service.

14. Governing law

These terms are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction. If you are a consumer resident elsewhere, you keep the benefit of any mandatory protections of the law of your country of residence.

15. Changes

We may update these terms. We'll change the date at the top, and where a change materially affects your rights we will notify you in the app before it takes effect. Continuing to use DevPacs after that means you accept the revised terms.
