GDPR for Mobile Apps: What Indie Makers Actually Need to Do
GDPR has a reputation for being a problem only big companies with legal teams worry about. That's wrong — and if you're a solo maker publishing to global app stores, the law almost certainly applies to you. The good news is that compliance for a typical indie app is far more achievable than the acronym soup suggests. This guide covers GDPR for mobile apps in plain terms: when it applies, what you actually have to do, and a checklist to get there without a lawyer on retainer.
The one-line answer: if any of your users are in the EU or EEA, GDPR applies to you regardless of where you live, and at minimum you need a clear privacy policy, a lawful basis for the data you collect, genuine opt-in consent for tracking, and a way to honor user requests to access or delete their data. This post sits in our privacy cluster alongside the app privacy policy generator, which handles the document side.
This is practical guidance, not legal advice. For anything high-risk — health data, children's data, large-scale profiling — talk to a qualified lawyer.
Does GDPR apply to my app?
Almost certainly, if you distribute through the App Store or Google Play. GDPR is extraterritorial — it applies based on where your users are, not where you or your business are. The moment someone in the EU or EEA installs your app, you're processing the personal data of an EU resident, and the law is in scope.
Because both stores distribute globally by default, "I'm just a solo developer in another country" doesn't get you out of it. Your options are to comply, or to explicitly geo-restrict your app so it isn't available in the EU — which most makers don't want to do.
What counts as "personal data"?
Broader than most people assume. Under GDPR, personal data is anything that can identify a person, directly or indirectly:
- Name, email, phone number, postal address
- User account IDs and profile data
- Device identifiers (advertising ID, IP address)
- Location data
- Analytics and usage data tied to a person or device
- Photos, contacts, or anything users upload
If your app touches any of these — and nearly every app touches at least device identifiers or analytics — you're processing personal data.
The core GDPR requirements for an app
You don't need to memorize the whole regulation. For a typical indie app, compliance comes down to a handful of obligations.
| Requirement |
What it means for your app |
| Lawful basis |
Have a legal reason to process each type of data (usually "consent" or "contract/necessity") |
| Transparency |
A clear, accessible privacy policy explaining what you collect and why |
| Consent |
Opt-in, freely given consent before non-essential tracking or ads |
| Data minimization |
Only collect what you actually need |
| User rights |
Let users access, correct, export, and delete their data |
| Security |
Protect the data with reasonable safeguards |
| Third parties |
Know what your SDKs and analytics tools collect on your behalf |
1. Establish a lawful basis
Every piece of personal data you process needs a lawful basis. For indie apps, the two that matter most are:
- Contract / necessity — data you genuinely need to deliver the service the user asked for (e.g., an email to create their account). No separate consent required.
- Consent — anything non-essential, like analytics tracking, advertising, or marketing emails. This requires explicit opt-in.
The trap is treating everything as "necessary." Analytics and ad tracking are almost never necessary to provide the service, so they need consent.
2. Publish a clear privacy policy
Transparency is non-negotiable, and both app stores require a privacy policy URL anyway. It must explain, in plain language, what data you collect, why, who you share it with, how long you keep it, and how users can exercise their rights. If you're unsure whether you even need one, our guide on whether you need a privacy policy for your app covers the store rules; the short version is yes. You can generate a GDPR-aware policy with a hosted URL using Adalo Studio's privacy policy generator instead of writing it from scratch or paying a lawyer for boilerplate.
3. Get real consent for tracking
This is where most apps slip up. Valid GDPR consent must be:
- Opt-in — no pre-ticked boxes, no "by using this app you agree."
- Freely given — you can't withhold core functionality to force consent for tracking.
- Specific and informed — users know exactly what they're agreeing to.
- Easy to withdraw — as simple to revoke as it was to grant.
In practice, that means a consent prompt before you fire up analytics or ad SDKs, and a settings screen where users can change their mind. Note that on iOS, Apple's App Tracking Transparency (ATT) prompt is a separate Apple requirement — showing it doesn't satisfy GDPR consent, and vice versa. You may need both.
4. Honor user rights
GDPR gives users rights over their data, and you need a way to act on requests:
- Access — provide a copy of their data.
- Rectification — correct inaccurate data.
- Erasure — delete their data ("right to be forgotten").
- Portability — export their data in a usable format.
For a small app, a monitored support email where users can make these requests is often enough — you don't need an automated portal on day one, just a reliable process. Note that Apple and Google now also require an in-app account-deletion path for apps that support account creation, which overlaps neatly with the erasure right.
5. Watch your third-party SDKs
Your analytics, crash-reporting, and ad SDKs collect data on your behalf, and you're responsible for it. Before launch, list every third-party service in your app and check what each collects. This same inventory feeds directly into your Google Play Data Safety section and Apple's privacy nutrition label, so doing it once serves three purposes. Minimize what you can — every SDK you drop is one less compliance liability.
A practical GDPR checklist for indie apps
- [ ] Confirm EU/EEA users can reach your app (they almost always can)
- [ ] Inventory every type of personal data you collect, including via SDKs
- [ ] Assign a lawful basis to each (necessity vs. consent)
- [ ] Minimize collection to what you truly need
- [ ] Publish a clear, GDPR-aware privacy policy with a live URL
- [ ] Add an opt-in consent prompt before non-essential tracking
- [ ] Provide a way to withdraw consent in settings
- [ ] Set up a process to handle access, correction, and deletion requests
- [ ] Add in-app account deletion (also required by both stores)
- [ ] Keep the ATT prompt (iOS) separate from GDPR consent
- [ ] Use reasonable security to protect stored data
Work through that list and a typical indie app is in solid shape. GDPR feels intimidating because of how it's written, but the operational reality for a small app is: collect less, be honest about it, ask before you track, and let people delete their data. For the rest of your legal and store paperwork, keep the app store submission checklist handy so nothing slips through before you hit submit.
Frequently asked questions
Does GDPR apply to my app if I'm not in Europe?
Yes, if any of your users are in the EU or EEA. GDPR applies based on where your users are, not where you or your company are located, so a solo developer anywhere in the world falls under it the moment a European user installs the app. Because app stores are global, most apps are reachable by EU users by default.
What is the difference between GDPR and a privacy policy?
A privacy policy is a document that tells users what data you collect and why; GDPR is the law that, among other things, requires you to have that policy and to follow specific rules like obtaining consent and honoring deletion requests. Publishing a privacy policy is one requirement of GDPR compliance, not the whole of it. You also need a lawful basis for processing, consent for tracking, and a way to handle user data requests.
Do I need consent before collecting any data in my app?
You need explicit, opt-in consent before collecting personal data for purposes like analytics tracking, advertising, or anything non-essential — and consent must be freely given, specific, and as easy to withdraw as to give. You do not need consent for data that is strictly necessary to provide the service the user requested, which relies on a different lawful basis. Pre-ticked boxes and 'by using this app you agree' notices do not count as valid consent.
