Your data stays on your phone.
Lock In has no accounts, no servers and no analytics. Your stats, activities and notes are written to your device and read back from your device. Nothing else happens to them.
The short version
- Everything you enter is stored on your device and nowhere else.
- There is no account, no login and no email address to give.
- No analytics, no advertising, no tracking of any kind.
- Payments go through Google Play. We never see your card details.
- You can export or delete everything yourself, from inside the app.
Lock In was previously called ShowUp
ShowUp was version 1 of this app. Lock In is version 2 — the same developer, the same Google Play listing, rebuilt around stats and ranks instead of daily check-ins.
If you used ShowUp, your old check-in history is still on your device but is not readable by Lock In, because the two store their records differently. Nothing was uploaded anywhere at any point, and nothing was shared with anyone.
What we do not collect
Lock In has no user accounts, no login, no backend server and no cloud database. There is nothing for us to collect, and we collect nothing:
- No name, email address, phone number or any other identifier
- No location data
- No advertising ID
- No usage analytics or behavioural tracking
- No crash reports sent to us or to anyone else
- No access to contacts, camera, microphone or any sensor
What is stored on your device
Lock In keeps the following in its own private storage area on your phone, which Android prevents other apps from reading:
- Your stats — the names and icons you chose, and the XP each has earned
- Your activities — what you wrote, the difficulty you picked, and when you finished them
- Any daily notes you write
- Achievements you have unlocked
- Your streak and freeze charges
- App preferences, and whether your subscription is active
To be precise about what this does and does not mean: this data is not separately encrypted by us. It is protected by Android's own app sandbox, which stops other apps reaching it. On a rooted device, or one where someone has physical access and your screen lock, that protection is weaker.
If you uninstall Lock In, all of it is deleted with the app. We hold no copy and cannot recover anything for you.
Subscriptions and purchases
Lock In offers optional premium subscriptions and one-time purchases that unlock past weeks and months. Every payment is processed by Google Play.
We never receive, store or have access to your card details, billing address or any financial information.
RevenueCat
Purchases are managed through RevenueCat, a service that verifies with Google Play whether your subscription is active. To do that, RevenueCat receives:
- An anonymous ID that Lock In generates for your installation
- Your device type, operating system version and country
- Purchase receipts from Google Play
That anonymous ID is not linked to your name or email, because Lock In never asks for either. Nothing you write in the app — no stat, no activity, no note — is ever sent to RevenueCat. Their handling of this data is covered by RevenueCat's privacy policy.
Exporting and deleting your data
You control all of it, at any time.
- Export — Settings writes a backup file to your Downloads folder. It is signed, so a file edited by hand will be refused on import.
- Import — restores a backup on any device, including a new phone.
- Delete — uninstall the app, or clear its data from Settings on your phone.
Once a backup file is on your device it is an ordinary file. If you send it somewhere or save it to a cloud drive, it goes wherever you put it. That is your choice to make and outside what the app controls.
Notifications
This version of Lock In does not send notifications. If reminders are added later, they will be generated on your device by your device — nothing about them would be sent anywhere, and this page would be updated before that shipped.
Other services
Besides RevenueCat, Lock In relies on:
- Google Play Billing — processes subscriptions and purchases
- Google Play Services — required to distribute any Android app
Both are governed by Google's own privacy policy. Lock In does not use Google Analytics, Firebase Analytics, Crashlytics, Sentry, the Meta SDK, or any other analytics or advertising service.
Cloud sync
There is no cloud sync. Your history lives on one device, which is why exporting a backup matters before you switch phones.
If sync is ever added it will be optional, it will require an account you deliberately create, and this page will be updated to say exactly what is stored and where before it is available.
Children
Lock In is not directed at children under 13, and we do not knowingly collect information from them. Since the app collects nothing at all and has no accounts, there is nothing held about any user of any age.
If you are a parent or guardian with a concern, the app's data lives only on the device — clearing the app's data from that phone's settings removes all of it immediately.
Changes to this policy
This page will be updated if the app starts handling data differently — most likely if cloud sync or notifications are added. The date at the top always reflects the current version.
Anything that changes what happens to your data will be announced in the app before it takes effect, not quietly published here.
Contact
Questions about this policy or about how Lock In handles your data can go to the developer contact listed on the app's Google Play page.
We aim to reply within five working days.
