App Maintenance Update Agreement Template

Parties & Application Overview

This section identifies the App Owner (the individual or company that owns the mobile or web application and its App Store / Google Play listings) and the Maintenance Provider (the agency, studio, or freelance developer responsible for keeping it running). It names the specific application by its app store listing name, bundle ID / package name, and current live version number at signing, and states which platforms are covered, iOS, Android, and/or web/PWA, since maintenance scope, App Store review timelines, and OS-support windows differ meaningfully between them. Multi-platform apps should list each platform's minimum supported OS version separately as an exhibit, along with the backend/API environment (staging vs. production) the maintenance work applies to, so there's no ambiguity about which build is actually covered.

Scope of Maintenance & Update Services

Defines exactly what 'maintenance' includes so neither party assumes free feature work is bundled in. Typical inclusions: bug and crash fixes reported through the crash-reporting tool named in the agreement (e.g., Crashlytics, Sentry); security patching for the app and its backend/API; dependency, library, and SDK updates; performance and uptime monitoring; and minor UI corrections that don't change functionality. Typical exclusions, called out explicitly to prevent scope creep: net-new features, full redesigns, adding a new platform build the app doesn't currently have (for example, adding Android support to an iOS-only app), backend infrastructure migrations, and integrating new third-party services. Any work outside this list is quoted separately using the app owner's standard change-order or scope-of-work process rather than absorbed into the maintenance retainer, and this section should say so explicitly to avoid the single most common billing dispute in ongoing app support relationships.

Release Cadence & Update Types (Patch, Minor, Major)

Sets the rhythm of releases so the app owner can plan launches, marketing pushes, and store listing updates around them instead of receiving surprise updates. Patch releases (crash fixes, critical bugs) typically ship within 48-72 hours of confirmation; minor releases (small improvements, dependency bumps, low-risk fixes) ship on a fixed schedule such as every 2-4 weeks; major releases (bundled feature sets, redesigns, adoption of a new OS version's design language) ship quarterly or per a separately scoped roadmap agreed outside this retainer. The agreement should state who has final approval over release timing and content before App Store/Play Store submission, whether a staged rollout percentage is used for major releases, and what the rollback plan is if a release causes a regression, including the maximum time allowed to publish a rollback build once a regression is confirmed.

OS Compatibility & App Store / Play Store Release Cycle

This is the section most generic 'software maintenance agreement' templates skip entirely, and it is the single biggest source of disputes on mobile app retainers, because it's where store-level obligations, not the app owner's product roadmap, force the schedule. It should specify: (1) the minimum iOS/Android OS versions the app commits to supporting, and how many business days after Apple or Google ships a new OS version the provider will test and certify compatibility; (2) who owns App Store Connect and Google Play Console submissions, and the target turnaround for resubmitting after a rejection, since Apple review typically runs 24-48 hours per attempt and repeated rejections compound quickly into missed launch windows; (3) a defined crash-free session rate threshold (for example, 99.5%) that triggers an out-of-cycle emergency patch obligation rather than waiting for the next scheduled release; and (4) responsibility for maintaining push notification certificates, API keys, and third-party SDK versions that Apple and Google periodically deprecate and force-update on a timeline neither party controls.

Support Response Times & Severity Levels (SLA)

Establishes a severity ladder so both sides agree on urgency without a negotiation every time something breaks. A typical structure: Severity 1 (app crashing on launch, payment flow down, or a core flow completely broken) acknowledged within 1-4 hours with a fix shipped within 24-48 hours; Severity 2 (a feature broken but a workaround exists) acknowledged within 1 business day and fixed in the next patch release; Severity 3 (cosmetic or low-impact bugs) bundled into the next scheduled minor release. The agreement should also name the reporting channel, a ticketing system, shared inbox, or the client portal the app owner will use to log issues, the support hours and time zone coverage the provider commits to, and whether after-hours or weekend coverage for Severity 1 issues is included or billed at a premium rate.

Fees, Included Hours & Overage Billing

Most app maintenance agreements are billed as a fixed monthly retainer that includes a set number of support hours (commonly 5-20 hours per month depending on app complexity and user base), with additional hours billed at a stated hourly rate. This section should specify what counts against the hour bank (bug triage, testing, release management, and app store submissions typically do; discovery calls for new feature scoping typically do not), how unused hours are handled from month to month (rollover vs. forfeited, and any rollover cap), and how OS-forced compatibility work, which the app owner didn't request but must be completed to stay listed in the app stores, is billed, since it is neither a bug fix caused by the provider nor a new feature requested by the client.

Data, Privacy & Compliance Updates

App store platforms periodically require updated privacy disclosures, Apple's App Privacy nutrition labels and Google Play's Data safety section, and enforce new SDK/API deprecations tied to privacy rules such as App Tracking Transparency prompts and Android's annual target API level minimum. This section assigns responsibility for keeping these disclosures accurate as the app's actual data collection and third-party SDKs change over time, and for meeting Google Play's target-API-level requirement each year, which can otherwise get an existing app pulled from new installs, or removed from the store entirely, with little warning if maintenance lapses. It should also cover who is responsible if a data breach or vulnerability disclosure requires an emergency patch outside the normal release cadence.

Term, Renewal & Termination

Most app maintenance agreements run 6-12 months with automatic renewal unless either party gives 30-60 days' written notice before the renewal date. Because live apps degrade quickly without maintenance, unpatched OS incompatibilities or an expired push certificate can functionally break or de-list an app within weeks, this section should also cover a formal offboarding handover: source code and its repository access, App Store Connect and Google Play Console admin access, code-signing certificates, push notification keys, and any third-party API keys must transfer back to the app owner, or to a new incoming provider, before the effective termination date rather than after, so there is no maintenance gap during a transition between providers.
