Privacy Policy

Effective October 11, 2026

TimeLens is an iPhone and iPad app that helps you estimate how long things take, time them, and get to places on time. This policy explains what information TimeLens handles, why, who else is involved, how long it's kept, and the choices you have. It applies to the TimeLens app and to timelensapp.pages.dev.

Who is responsible

TimeLens is published by Alhassane Balde, an individual developer based in New York, United States ("we", "us"). We decide how your information is used and are responsible for it.

Contact: timelensfeedback@gmail.com

The short version

• We collect what TimeLens needs to work: your account, the sessions and commitments you create, and your subscription status.
• Usage and crash data is collected only if you say yes, and you can turn it off at any time.
• Your calendar, your location, your travel times and your onboarding answers stay on your device.
• We don't sell your information, show ads, track you across other apps or websites, or share your data with data brokers.
• You can export your data, and you can delete your account and its data from inside the app.

What we collect, and why

Account information. Your email address, your first name, and, if you choose to add it, your last name. If you sign up with email, you also create a password; it is stored only in hashed form by our authentication provider, and we can't see it. If you sign in with Apple or Google, we receive your account identifier from that provider and, if you share them, your name and email address (Apple may give us a private relay address instead of your real one). We use this to create and secure your account, sign you in, and show your name in the app.

Your age. When you sign up, you enter your date of birth so we can confirm you're at least 13. This is checked on your device and is not stored or sent to us.

Sessions you track. For each session: the task name, your time estimate, start and end times, how long it took, your confidence rating, the distraction level and time you record, any notes you write, and whether it's archived. For transitions (getting to a commitment), the planned and recorded times of each step. We use this to show your history and Insights, calculate your TimeLens Score, and keep your data in sync across your devices.

Commitments you add. The name, days and times, place name, the address and map coordinates of the place if you pick one, how you'll get there, the time you plan for each step, your reminder setting, notes, and which occurrences are done or skipped. We use this to plan when to get ready and leave, remind you, and sync across your devices.

Subscription status. Apple processes all payments. Apple tells us which plan you have, whether it's in a free trial, and when it renews or ends, together with transaction identifiers, so we can unlock the app for your account. We never receive your payment card or billing details.

Sign in with Apple token. If you sign in with Apple, we may store a token Apple issues, so we can revoke TimeLens' access to your Apple account when you delete your TimeLens account.

Usage and crash data (only if you agree). TimeLens asks once whether you want to share this, and you can change your answer at any time in Account → "Share usage & crash data". If you agree, we record basic app events: the app being opened, signing up or in (and which sign-in method), finishing the welcome steps, viewing the subscription screen, completing a purchase (which plan, and whether it's a trial), and starting or saving a session (its type, and whether it had an estimate). Each event has a time and the app version, and is linked to your account. If you have also turned on Settings → Privacy & Security → Analytics & Improvements → "Share with App Developers" on your device, iOS gives TimeLens crash, hang and performance reports (such as device model, iOS version, technical crash details, launch time and memory use), which we store linked to your account. These records never include task names, notes, commitments, places or times you tracked. We use them only to understand how the app is used and to fix problems. The app events (not the crash and performance reports) are also sent to PostHog, our analytics provider, under a coded identifier instead of your name, email address or account ID. If you say no, nothing is collected, and turning it off discards anything not yet sent.

Messages you send us. If you email us, we receive your email address and whatever you write, and use them only to reply and to improve TimeLens.

We don't ask for health information. TimeLens is designed with ADHD and time blindness in mind, but it never asks whether you have a diagnosis or condition. Please don't include health details in task names or notes.

What stays on your device

These are used only on your iPhone or iPad and are never sent to us:

• Calendar. If you allow it, TimeLens reads events from the calendars you choose, to plan when to get ready and leave. It never changes your calendar.
• Location. If you allow it, TimeLens uses your location while you're using the app to ask Apple Maps how long it takes to get somewhere. If you also turn on "Notice when I leave and arrive", iOS watches the area around your starting point and destination during a transition. Your location is never sent to or stored by us.
• Travel time estimates, and places found for calendar events. Kept on your device; cleared when you sign out.
• Onboarding answers. Used to tailor the welcome screens. They're not stored.
• Preferences, reminders and Live Activities. Notifications are scheduled on your device by iOS. We don't use push notifications and don't receive a push token.

Who else is involved

We don't sell or rent your information, and we don't share it for advertising. We use these service providers, only to run TimeLens:

• PostHog: product analytics, only if you agreed to share usage data. It receives the app events described above, under a coded identifier, so we can see how the app is used (for example, where people stop during setup). We ask PostHog not to store your IP address or work out your location from it. It never receives your name, email address, sessions, notes or commitments.
• Supabase: our database and authentication provider. It stores your account, sessions, commitments, subscription status and, if you agreed, usage and crash data.
• Apple: payments and subscriptions (App Store), Sign in with Apple if you use it, and Apple Maps travel-time estimates. When TimeLens asks Apple Maps for a route, Apple receives your current location and the destination, under Apple's privacy policy.
• Google: Google Sign-In, only if you choose it. Google's sign-in page opens in a secure browser window and Google shares your account identifier, name and email address with us under Google's privacy policy.

We may also disclose information if the law requires it, to protect the rights, safety or security of our users or others, or as part of a transfer of TimeLens to a new owner, who would have to keep this policy's commitments.

Where your data is stored

Our providers may store and process information in the United States and other countries. Where the law requires it, we rely on appropriate safeguards for international transfers, such as the European Commission's standard contractual clauses used by our providers.

How long we keep it

• Your account, sessions, commitments and subscription status are kept while your account exists.
• When you delete a session or commitment, its content is removed from our servers. A marker with only its identifier and dates stays until your account is deleted, so your other devices know it was deleted.
• Usage and crash data is kept while your account exists. Usage events in PostHog are kept for up to one year; ask us and we'll delete them sooner.
• When you delete your account, all of the above is deleted. Copies may remain in our provider's encrypted backups for a limited time before they are overwritten.

Your choices and rights

You can, at any time:

• Export your data: Account → Data & Storage → Export Data (PDF or CSV).
• Correct it: edit sessions, commitments and your name in the app.
• Delete it: delete individual items, or your whole account in Account → Manage Account → Delete Account. See "Your Data & Deletion" in the app for exactly what happens.
• Stop optional collection: turn off "Share usage & crash data", and change calendar, location and notification access in iOS Settings.

Depending on where you live, you may have additional rights. If you're in the European Economic Area, the United Kingdom or Switzerland, you can ask to access, correct, delete or receive a copy of your data, restrict or object to how we use it, and withdraw consent at any time (this doesn't affect anything done before). You can also complain to your local data protection authority. Our legal bases are: performing our contract with you (your account, syncing and the app's features), your consent (usage and crash data, and the calendar and location access you grant), and our legitimate interests in keeping TimeLens secure and working, balanced against your rights.

If you're a California resident, you have the right to know what personal information we collect and how we use it, to delete it, to correct it, and not to be treated differently for using these rights. We don't sell personal information or share it for cross-context behavioral advertising, and we don't use or disclose sensitive personal information for anything beyond providing the app. Residents of other US states with privacy laws have similar rights.

To make a request, email timelensfeedback@gmail.com from the address on your account. We may need to confirm it's you. We'll answer within the time the law requires, normally within 30 days.

Security

Data travels between the app and our servers over encrypted connections (HTTPS). Our database provider encrypts stored data, and access rules make sure each account can only read and change its own data. Your sign-in tokens are kept in your device's Keychain. No method of transmission or storage is completely secure, but we work to protect your information and will tell you if a breach affects you, as the law requires.

Children

TimeLens is not for children under 13, and we don't knowingly collect information from them. If you believe a child under 13 has created an account, contact us and we'll delete it.

Changes to this policy

If we change this policy, we'll update the date above. If a change is significant, we'll tell you in the app before it takes effect.
