Privacy Policy
Effective November 13, 2026
- Odo needs no account and no sign-up.
- Your habits, streaks, bricks and settings are stored on your iPhone, not on our servers.
- Friend groups are optional. Only if you sign in to use them does Odo send anything to our server, and this policy lists exactly what.
- Odo never sees which apps you use. Screen Time data stays inside Apple's protected part of iOS.
- Apple Health data is read on your iPhone and never leaves it.
- There are no ads, no analytics SDKs and no tracking. We don't sell or share your data.
Who we are
Odo is made by Adsy LLC ("we", "us"). Adsy LLC is responsible for the app and this website. You can reach us at [email protected].
This policy covers the Odo app for iPhone and this website.
What the app stores, and where
Everything you create in Odo stays on your device, in the app's own storage and in a storage area shared with Odo's widgets and extensions on the same iPhone. That includes:
- Your habits, their goals, schedules and check-ins
- Streaks, stats and completion history
- Your blocks and focus sessions, and their levels and schedules
- Bricks, Odo's outfit, your plot and other customizations
- Your settings
Unless you sign in to use friend groups (see below), none of this is sent to us. It is included in your iPhone's own backups (iCloud or computer) if you have those turned on, under Apple's terms.
Screen Time
Odo uses Apple's Screen Time frameworks (Family Controls, Managed Settings and Device Activity) to block apps and websites, run focus sessions and show your screen time.
- When you choose apps, categories or websites, Apple gives Odo anonymous tokens. Odo can't read the names of the apps behind them.
- Screen time charts and the "Time back" numbers are drawn by a sealed extension that Apple runs on your iPhone. Apple doesn't let that extension send anything out, and the numbers can't be passed back to the rest of the app.
- Odo records simple events on your device, such as when a block starts or ends, when you unlock early, or when Screen Time access is turned off, so it can keep your streaks accurate.
None of this leaves your iPhone.
Apple Health
If you connect Apple Health, Odo asks for read access only to the types you use, such as steps, sleep or water, at the moment you first use them. Odo doesn't write anything to Health.
- Health data is read on your iPhone to count your habits and fill your My Health dashboard.
- It is never sent to us or anyone else, never stored in iCloud by Odo, and never used for advertising or data mining.
- You can change or remove access at any time in the Health app or in iOS Settings → Health → Data Access & Devices.
Friend groups and your account
Friend groups are an optional feature in versions of Odo that include it. They let a small private group of people you invite compete on weekly focus time. To use them you sign in with Apple, which creates an Odo account on our server. If you never sign in, nothing in this section applies to you.
When you are signed in, our server stores:
- Your sign-in: the anonymous user ID Apple gives us for Odo, and a sign-in token so we can end the link with Apple if you delete your account. We never see your Apple Account password.
- Your display name, which you can change in Settings.
- Your email address, only if you turn on "Email me tips and offers" when signing in. Otherwise we don't ask Apple for it. If you chose Hide My Email, we only get Apple's relay address.
- What your groups see: the names, icons, colors and streaks of your habits and blocks, whether each is done today, the share of habits you kept this week and last, Odo's outfit, your level, your plot, and feed items such as reaching a milestone or ending a block early.
- Your focus sessions: start and end times, the level, and how each ended, so the server can count your focus minutes for the weekly race.
- Group details: the groups you are in, when you joined, your emoji reactions, the emoji nudges you send and receive, race results and bricks won.
- A notification address: the token Apple gives Odo for sending notifications to your iPhone, so a nudge can reach you. It is removed when you sign out. A nudge passes through Apple, and contains only the group's name, the sender's name and the emoji.
- Technical data: your time zone, so weeks and days are counted correctly, and a record of the devices signed in to your account.
What stays on your iPhone even when you are signed in: Apple Health data, Screen Time data, which apps or websites you block, and anything in Odo that isn't in the list above.
Who can see it. Only members of groups you are in can see your name and the shared items above. Groups are private, limited to 12 people, and joined only with an invite link or code. Anyone who has the invite can join, so share it only with people you want in the group. There is no public profile and no search.
Email. If you opted in, we may email you tips, news and offers about Odo. You can turn this off at any time in Settings in the app, or with the unsubscribe link in any email. We never use Health or Screen Time data to decide what to send you.
Where it is kept. The server runs on Cloudflare, which processes this data for us, and the database is located in Western Europe. Data is encrypted in transit.
How long. We keep account data until you delete your account. Signing out or deleting the app from your iPhone does not delete your account.
Deleting your account. In the app, go to Settings → Account → Delete account. This removes your account, your shared profile, your focus sessions and your place in every group from our server straight away. Your line is also taken out of the past weekly results of groups you were in. If you can't use the app, email us and we'll delete it for you.
Notifications
Reminders and block heads-ups are scheduled on your iPhone as local notifications. The one exception is friend groups: a nudge from someone in your group is delivered through Apple's push notification service. You can turn notifications off in iOS Settings.
Purchases
If you make an in-app purchase, such as a tip, Apple handles the payment. We never see your name, card or Apple Account details. Apple shares only anonymous sales reports with us.
Crash reports and diagnostics
Odo contains no analytics or crash-reporting libraries. If you choose to share analytics with app developers in iOS Settings → Privacy & Security → Analytics & Improvements, Apple may share anonymous crash reports and usage statistics with us. We use them only to fix problems.
When you email us
If you contact support, we receive your email address and whatever you write, plus the app and iOS version that Odo adds to feedback emails. We use this only to answer you, and we delete support emails when they're no longer needed.
This website
This site has no cookies, no analytics and no third-party scripts or fonts. It is hosted by Cloudflare, which processes basic technical data such as IP addresses to deliver the site and protect it from attacks. See Cloudflare's privacy policy.
What we don't do
- We don't show ads or use advertising identifiers.
- We don't track you across apps or websites.
- We don't sell, rent or share personal data.
- We don't use your Health or Screen Time data to train AI models.
Your choices and rights
Because almost all of your data lives on your iPhone, you control it directly:
- Delete it: delete Odo from your iPhone and its data on the device is removed. Data inside your device backups follows those backups. If you signed in for friend groups, delete your account first in Settings → Account.
- Leave or sign out: you can leave any group, turn off emails or sign out at any time in the app.
- Stop access: turn off Screen Time, Health or notification access in iOS Settings at any time.
- Ask us: depending on where you live (for example under the GDPR in the EU and UK, or the CCPA in California), you may have rights to access, correct or delete personal data we hold. In practice the only personal data we may hold is your support emails and, if you signed in, the account data described under Friend groups and your account. Write to us and we'll help.
Children
Odo is meant for adults and teens managing their own habits. It isn't directed at children under 13, and we don't knowingly collect personal data from them.
Future features
We plan to add versions for iPad, Mac, Android and Windows, with syncing between them, and more ways to compete in friend groups. Before any of that ships, we'll update this policy, explain exactly what is shared, and ask you first. Apple Health data will not be shared with friend groups without your clear consent.
Changes to this policy
If we change this policy, we'll post the new version here and update the date at the top. If a change is significant, we'll also tell you in the app.
