How to Write a Terms of Service for a Mobile App

A mobile app terms of service is not the same document as a EULA, and it is not the same document as a privacy policy, even though app owners frequently try to make one document do all three jobs. A EULA is a software license: it grants permission to install and run the app. A privacy policy discloses what data the app collects. A terms of service governs the relationship between the app owner and the user while the app is actually being used: what an account is for, when it can be terminated, what happens to a user's content, how in-app purchases and subscriptions are billed, and how a dispute between the two of you gets resolved. Generic terms of service templates written for websites cover accounts, acceptable use, and liability well enough, but they are usually silent on the four areas that matter most for an app distributed through the App Store or Google Play. Here is what to add for each one.

Account termination and content removal rights

Every mobile app terms of service needs to state, plainly, who can end the relationship and under what conditions. That cuts both ways: a user needs to know they can delete their own account, and you need the contractual right to suspend or terminate an account that violates your terms, without that decision turning into a breach-of-contract dispute. State both directions separately rather than relying on a single vague "we reserve the right to terminate" line, since a reader (and a court, if it ever comes to that) benefits from knowing what specifically triggers removal versus what a user can do on their own initiative.

Content removal deserves its own clause, distinct from account termination, because the two do not always happen together. An app with any user-generated content, comments, photos, listings, profile text, needs the right to remove a single piece of content without terminating the account that posted it, and the terms should say so. A moderation decision that only has one lever, delete the whole account, either gets used too aggressively for minor violations or not at all because the penalty feels disproportionate to the problem. Giving yourself a graduated set of actions, content removal, warning, temporary suspension, permanent termination, and stating that graduation in the terms, is both fairer to users and easier to defend if a removal decision is ever challenged.

Also address what happens to a user's own data and content on termination, since this is the question users actually ask when an account is deleted or suspended. Say whether content is deleted immediately, retained for a stated period in case of an appeal, or, for content that involves other users (a marketplace listing someone already purchased, a comment thread others replied to), left in place with attribution removed. Leaving this unaddressed is one of the most common gaps in a mobile app's terms, and it is one of the easiest to close with a single clear paragraph.

In-app purchase and subscription billing terms

If your app sells anything through Apple's or Google's in-app purchase systems, consumable items, a one-time unlock, or an auto-renewing subscription, your terms of service need to describe the billing relationship accurately, and that description has to match how App Store Connect and Google Play Console actually process the purchase. This is one of the few places where a generic SaaS billing clause, written for a card charged directly by your own payment processor, is simply wrong for a mobile app: Apple and Google are the merchant of record for in-app purchases, they handle the transaction and the refund request, and your terms should not promise a refund process you do not control.

The distinction that most templates get wrong is treating a consumable purchase and an auto-renewing subscription as the same kind of transaction. They are not, and both platforms require different disclosures for each.

For a subscription specifically, both Apple and Google require the terms to state the length of the subscription period, the price, and that it renews automatically unless the user cancels before the renewal date, and this information generally needs to be visible at the point of purchase, not only buried in a terms document a user never opens. Your terms of service should still state it in full, because that is the reference document a user or a platform reviewer checks against the purchase flow when something is disputed. Say clearly that cancellation must be done through the App Store or Google Play account settings, not by contacting your support team, since that is where the platform actually processes it, and a terms document that implies otherwise sets up a support request you cannot fulfill.

User-generated content standards

Any app with a way for users to post something visible to other users, a comment, a photo, a profile bio, a marketplace listing, needs a user-generated content section that does two jobs: it grants you the license you need to display and operate on that content, and it sets the behavioral standard users are agreeing to follow. Both App Store Review Guideline 1.2 and Google Play's User Generated Content policy specifically require apps with UGC or messaging features to have content moderation tools, a reporting mechanism, and terms that give the app owner a stated basis for removing objectionable content, so this section is not optional boilerplate for a social feature, it is a store review requirement.

The license grant itself should be specific about scope: a limited, non-exclusive, license to host, display, and distribute the content within the app for the purpose of operating the service, not a broad, perpetual, all-rights grant that a user reasonably wondering "can they sell my photos" would object to if they actually read it. Vague UGC language causes two different problems: it either grants you rights broader than you need and erodes user trust if anyone reads it closely, or it is too thin to give you a clear basis for removing content that violates community standards.

The standards themselves should be a short, specific list, not a single catch-all sentence: no illegal content, no harassment or hate speech, no impersonation, no spam, and whatever else is specific to your app's actual content surface. A dating app needs a different UGC standard than a project management tool with comment threads, so write the list to match what your app's content feature actually allows someone to post, rather than copying a generic list that does not fit.

Arbitration and dispute resolution language

An arbitration clause routes disputes between you and a user to binding arbitration instead of a court, and for a mobile app with a large number of individual users, it is one of the more consequential clauses in the whole document, since it typically also includes a class-action waiver, meaning users agree to bring claims individually rather than as part of a group. Whether to include one is a business and legal decision beyond the scope of a drafting guide, but if you do include one, the terms need to state the arbitration provider, the governing rules, and give users a clear opt-out window, typically 30 days from account creation, during which a user can decline arbitration in writing and preserve their right to sue in court instead.

The opt-out window matters for enforceability. Some jurisdictions and courts have been more willing to enforce an arbitration clause when a user had a genuine, clearly disclosed opportunity to decline it, versus a clause presented as a non-negotiable condition of using the app at all. State the opt-out mechanism plainly, an email address to send the opt-out notice to, and the deadline, rather than leaving it implied or omitting it entirely. Also state whether the clause applies to all disputes or carves out small-claims court, which many arbitration clauses exempt so a low-dollar dispute does not require either side to hire an arbitrator.

Putting it together

A mobile app terms of service earns its keep by covering the four areas a generic web template usually misses: a graduated account termination and content removal policy instead of a single all-or-nothing clause, billing language that matches how Apple and Google actually process in-app purchases and subscriptions, user-generated-content standards specific enough to both grant the license you need and give users real notice of what is and is not allowed, and, if you use one, an arbitration clause with a real opt-out window rather than a buried non-negotiable term.

Our Terms of Service Generator includes fields for account termination, content removal, in-app purchase and subscription billing, and dispute resolution, so a mobile app can produce terms that actually reflect how accounts, purchases, and content moderation work in your app rather than describing a generic website. It pairs well with the platform-specific groundwork in our mobile app EULA guide if you are drafting both documents for the same app store submission.
