Sex Tracker Apps in a Privacy Check (2026)
A sex tracker is a private digital diary for intimate encounters. Because the most sensitive data of all ends up there (Article 9 GDPR), it is not the feature list that decides which app is right – but the question of where the data lives.
The four questions that count
1. Does the app need an account? Every account links your entries to an identity. 2. Does data leave the device? "Local" is only true if there is no provider server. 3. What does the data safety label say? The providers' store listings are more binding than any marketing page. 4. Is there an app lock? Against the curious glance when the phone lies around unlocked.
The comparison
| App | Platform | Account? | Where does the data live? | Store label (quoted, as of 23 August 2026) |
|---|---|---|---|---|
| Intimassy | iOS + Android | Yes | Device + provider cloud | Apple label: among others user ID, device ID, contact info, photos and "Sensitive Info" as Data Linked to You |
| HookBook | Apple only | No | Device + the user's own iCloud | "Data Not Collected" |
| Sex Tracker & Calendar | Android | No | Device only, no backup | "No data collected" – but also: "Data isn't encrypted", "Data can't be deleted" |
| Fapstats | Android | Yes | Provider cloud | collects, according to the label, location and personal data among others |
| SexLife Tracker | Android | No | Device only | "No data collected" |
| Love the World | Web/PWA (all) | No | Device (AES-encrypted) + optionally the user's OWN cloud | no account, no provider server for content – there is nothing a label could list |
How to read a data safety label
The labels are the most binding document that exists about an app: the provider fills them in and is liable for false statements. They are just not self-explanatory.
Apple: "App Privacy"
- "Data Linked to You" – this is the line that counts. If it says "Sensitive Info" or "Health & Fitness", intimate entries are linked to you.
- "Data Not Linked to You" – usually crash reports and usage statistics; harmless as long as no content is included.
- "Data Used to Track You" – advertising and analytics networks. In a diary app a deal-breaker.
- "Data Not Collected" – the best line. It means: nothing leaves the device in the direction of the provider.
Google: "Data safety"
- "Data collected" and "Data shared" – two separate lists. Collected means: sent to the provider. Shared means: passed to third parties, usually advertising SDKs.
- "Data is encrypted in transit" – applies only to the way to the server, not to storage on the device or at the provider. If it says "not encrypted", entries travel the network in plain text.
- "You can request that data be deleted" – if this is missing, there is no way to get rid of your own entries at the provider. "Data can't be deleted" in the table above is exactly this line.
What "local" and "encrypted" really mean
Three phrases from marketing pages, translated. "Stored locally" is only a protection if the local database is encrypted too – otherwise anyone holding the device, or a backup on a computer, can read it. "Encrypted in transit" protects the way, not the destination: on the server the entry sits readable if the provider holds the key. "End-to-end encrypted" is the only promise under which the provider cannot read the entries – recognisable by the app warning that a lost key makes everything unrecoverable. The seven questions for checking a diary app completely are in their own guide (in German).
Checklist before installing
- Open the store label, not the website: which line sits under "linked to you"?
- Account required? If yes: for what – sync, or only marketing?
- Where do the entries live: device, your own cloud, provider server?
- Is there an app lock – and is the local database encrypted?
- Can you get back out: export and complete deletion?
What the check shows
The most striking gap is the distance between marketing and label: advertising pages say "private" and "encrypted locally" – the binding store listings of the same provider then list Sensitive Info, Data Linked to You. If you want to be sure, read the data safety label, not the marketing page. And: almost all offer an app lock (PIN/biometrics) – it protects against curious glances, but not against the provider. Only an architecture without an account and without a server protects you from the provider.
Our own standard
Love the World is a love diary as a world map: encounters are collected as pins on a spinning globe – by nation, not as a form with eleven fields. There is no account and no server for content; entries and photos are AES-256-encrypted on the device, the optional backup sits in the user's own Google Drive – and photos are technically never part of share links. The sentence "your data never reaches us" is therefore not a marketing line but a technical property. How sharing works without a server, with a real example link (in German).

Frequently asked questions
Is there an app to keep track of who you have slept with?
Yes, several – the table above compares the best known. The most important difference is not the feature set but where the data lives: only on your device, in your own cloud or on the provider's server.
Is a sex tracker app safe?
As safe as its architecture. Check: account required? Data on provider servers? What does the store label say? Is there an app lock? Apps without an account and without their own server technically cannot see your entries – that is the strongest guarantee.
Should I enter real names?
Better not – nicknames or initials are enough. Good apps do not ask for surnames or contacts anyway, and photos belong – if at all – only encrypted on your own device. What never reaches a server can never leak there.
What does "No data collected" mean in the store?
That the provider declares, bindingly, that the app transmits no data to them – neither content nor usage statistics. It is the best line a label can have. It says nothing about whether the data is encrypted on the device; the documentation has to answer that.
Is an app lock with a PIN or Face ID enough?
Against someone looking at your unlocked phone, yes – and that is the most common case. Against the provider, no: a lock protects the screen, not the server. Only an architecture without an account and without a content server protects you from the provider.
