Terms of Use
Last updated: October 26, 2026
These terms apply when you use the Lock In app. Lock In is run by Andrija Dmitrović, Serbia ("we"). By using the app you agree to them. How we handle data is in the Privacy Policy.
1. What Lock In is
Lock In helps you track your spending, keep a streak, plan your month and save for goals, alone or with friends. It is a tool for your own notes and habits. It is not financial, legal or tax advice, and it does not connect to your bank. The numbers are only what you enter.
2. The messages
Lock In comments on your spending, sometimes harshly (you choose how harshly in Settings: Mild, Normal or No mercy). The messages are meant as humour and motivation, not as a judgement of you.
3. Trial and subscription
- Lock In has a 7-day free trial. After it, using the app needs a paid subscription or a one-time purchase.
- You buy through the App Store or Google Play, and their terms apply to the payment, renewals, cancellation and refunds. Subscriptions renew automatically until you cancel them in your phone’s subscription settings.
- Deleting the app or your Lock In account does not cancel a subscription.
- Prices are shown in the app before you buy.
4. Your account
An account is only needed for shared goals and your subscription. You sign in with a code sent to your email, with Apple or with Google. Keep access to that email or account to yourself. You can delete your account at any time in Settings > Danger zone > Delete account.
5. Friends and shared goals
- Only invite people you know, and only to their own email address. Do not use invites to send spam.
- Everyone in a shared goal is equal: any member can rename it, change the target and add their own friends. Every member sees all payments into the goal. Anyone can leave at any time; their payments are removed.
- Do not use names, goal names or notes to insult, threaten or impersonate anyone.
Lock In limits how many invites, goals and payments can be made in a time, to stop abuse. We may suspend or delete accounts that break these rules.
6. Your data
Your spending stays on your phone, and you are responsible for it: if you lose or reset your phone without a backup, we cannot restore it. Use More > Backup to keep a copy.
7. Changes and availability
We keep improving Lock In and may change or remove features. We try to keep the shared goals service running, but cannot promise it will always be available.
8. Liability
Lock In is provided "as is". To the extent the law allows, we are not responsible for decisions you make based on the app or for losses from using it. Nothing in these terms limits rights you have under the consumer laws of your country.
9. Law
These terms are governed by the laws of Serbia, without taking away the protection of the consumer laws where you live.
