The short version: Your training data — workouts, settings, and history — stays on your device and is not sent anywhere. There are no accounts and no advertising. We do use privacy-light, cookieless analytics that count aggregate, anonymous usage (such as how many people open the app or log a workout) so we know what to improve — not your name, your numbers, or anything that identifies you.
Titan is an iOS app for iPhone that helps you run Jim Wendler's 5/3/1 strength-training program. It is free to use, with an optional Premium subscription. It tracks your lifts, training maxes, sets, history, and personal records, and works fully offline. A legacy web version of Titan also remains available at titanlift.app; this policy covers both.
All of your training data stays on your device. Everything you enter — your workouts, training maxes, history, program template, theme, and other settings — is saved in the app's private local storage on your iPhone (or, in the legacy web version, in your browser's local storage). This data is not transmitted to any server. We do not have a copy of it, and neither does anyone else, because it does not leave your device. (The cookieless usage analytics described below are separate, aggregate, and carry none of your training data.)
In plain terms: your training data does not leave your device. The only measurement performed is the cookieless, aggregate usage analytics described next — which carry no personal or training information.
To understand how Titan is used and where to improve it, we use two privacy-light, cookieless measurement tools. Neither sets cookies, tracks you across other websites, nor builds an advertising profile of you:
What is not sent: your name, training maxes, weights, reps, dates, notes, history, or any other content you enter. The app technically cannot send those — every analytics event is filtered through a fixed allowlist of the harmless settings listed above, and everything else is dropped before anything is transmitted. The result is aggregate counts that cannot be used to identify you. Vercel and PostHog process this data as our analytics providers.
Titan lets you export a backup of your data as a JSON file. This only happens when you explicitly tap Export. The backup file is saved to your own device through the normal iOS save/share flow (or your browser's download mechanism in the legacy web version), and it stays there. We don't receive it. If you later choose to move, copy, email, or share that file, that is entirely your decision and under your control.
If you bring your training history from another app (for example a Hevy or Strong export), the file is read and processed entirely on your device — it is not uploaded, and we do not see it. The same device-local promise that covers your Titan training covers your old app's data too. Imported history can be removed again at any time in Settings → Data.
Storing everything locally is great for privacy, but it has one important consequence: if you delete the app (or clear its data) and have no backup, your training data is gone — there is no copy on a server for us to restore. For that reason we strongly recommend exporting a backup periodically (or using the optional iCloud Backup described below), and keeping it somewhere safe. The app shows reminders to do this.
If you subscribe to Titan Premium, you can back up your training data to your own iCloud account. Your data is stored in your personal, private iCloud database via Apple CloudKit — it is not accessible to us and is not shared with any third party. Apple encrypts it in transit and at rest. Backing up is opt-in (you tap "Back up" or restore), requires that you are signed into iCloud on your device, and you can delete the backup at any time. There is still no account or login to Titan itself, and your data is not sent to our servers.
If you turn on workout reminders, Titan uses your device's built-in notification feature to remind you to train. These reminders are generated and shown locally by your own device. No reminder data is sent anywhere.
Titan will evolve, and this policy will evolve with it. Two things we are openly considering for the future: an optional server-side backup of your training data (so it can't be lost with a device), and using anonymised, aggregated training data to improve the training methodology and its predictions. If we introduce either of these — or change what the cookieless usage analytics above measure — we will update this policy to describe it before it happens. We don't use advertising trackers today and have no plans to introduce them.
