Privacy Policy
KnotGuide has no accounts and never asks who you are. Your saved knots and settings stay on your device and in your own iCloud (or, on Android, your phone’s backup) — we never see them. We count anonymous usage, such as which knots are opened and which step people stop at, to make the guides better. The free version shows ads from Google that are never personalized. Subscribers and lifetime owners never see ads.
What stays with you
- My List and your settings. The knots you save and your preferences (such as left- or right-handed steps and the tightening sound) are kept on your device. On iPhone and iPad, if you are signed in to iCloud, they also sync through your own private iCloud storage so they appear on your other devices. That storage belongs to your Apple Account; we cannot read it.
- Where you left off. The step you were on in a knot is kept only on that device, so you can pick up where you stopped. It is never synced or sent anywhere.
- Search. What you type in search is used only on your device to filter the list. It is never saved or sent anywhere.
If you sign out of iCloud or turn off iCloud for KnotGuide, iOS removes the synced copies from that device. Anything that finished syncing comes back when you sign in again with the same Apple Account.
On Android
The Android version does not sync live between devices. My List and your settings are included in Android’s own automatic backup, which Google stores in a private area of your Google Account that we cannot see, and they come back when you set up a new phone or reinstall. Where you left off in a knot is kept only on that phone and is left out of the backup. You can turn backup off in Android Settings.
You can also export My List and your settings to a file and import it on another device — for example when moving between Android and iPhone. The file is written only where you choose to save it, and nothing in it identifies you.
Anonymous usage statistics
KnotGuide uses Google Analytics for Firebase to learn how the guides are used. The app reports only a few events: a knot was started, a step was reached, someone went back a step, a knot was finished, a knot was added to My List, and the upgrade screen was shown. These events carry only which knot and which step, the number of steps, left- or right-handed, and whether a knot was resumed — never anything you type.
Like any app using it, Google Analytics also records a random ID it creates for this installation, your device model and system version, and an approximate region worked out from your IP address. We don’t set a user ID, don’t collect advertising identifiers or the vendor identifier for analytics, and have Google signals and ad personalization turned off, so this data isn’t linked to you and isn’t used to track you. See how Google Analytics safeguards data and Google’s privacy policy.
Purchases
Payments are handled entirely by Apple on iPhone and iPad, and by Google Play on Android. We receive no payment details, no card numbers and no billing address. The app checks on your device whether you have unlocked all knots; it does not store or send your purchase history anywhere, and it does not report purchases or prices to analytics. Purchases made on iPhone and iPad don’t carry over to Android, or the other way round.
Ads in the free version
Only the free version shows ads. They are served by Google AdMob and never appear while you are following a knot. Ads the app shows on its own start only after the app has been installed for three days; you can always choose to watch a short ad to open a locked knot for 24 hours. Once you subscribe or buy lifetime access, all ads stop and Google’s ad code is not started for you.
Ads are never personalized. KnotGuide asks Google for non-personalized ads only — chosen from the context of the app, not from a profile of you — and they are rated for general audiences. The app never asks for permission to track you and does not read your device’s advertising identifier (on Android, the advertising ID permission is removed from the app).
To serve ads, prevent fraud and measure them, Google’s ad code on your device sends Google:
- device and app information, such as a device identifier for this app, device model and system version;
- your approximate location, estimated from your IP address;
- which ads were shown and how you interacted with them;
- crash, performance and other diagnostic data from the ad code.
We don’t receive any of this, and we never give Google your list or anything about who you are. See how Google uses information from apps that use its services and Google’s privacy policy. KnotGuide does not use ad networks other than Google.
Your choices in Europe. If you are in the European Economic Area, the United Kingdom or Switzerland, Google’s consent form asks for your choice before any ad is requested. If you decline, you still get non-personalized ads. You can change your choice any time in KnotGuide’s Settings, under Ad Privacy Options.
Feedback
If you send us feedback from the app, it opens your own email app. We receive only what you choose to send — your email address and your message — and use it only to reply to you.
Children
KnotGuide is a general-audience app and is not directed at children. It has no accounts, no chat, no user-to-user content and no social features. Ads in the free version are rated for general audiences.
Your rights
Your list and settings live on your devices, in your iCloud, or in your phone’s backup, so they are yours to remove: deleting the app removes them from that device; on iPhone and iPad you can erase the app’s iCloud data in Settings under your name, then iCloud; on Android you can delete backups in your Google Account. The usage statistics are anonymous and not linked to you, so we cannot pick out yours; Google keeps them under its data retention rules and deletes them automatically. Data that Google’s ad code collects is held by Google under its privacy policy; in Europe you can change your ad choice any time under Ad Privacy Options. For anything else, write to us.
Changes
If a future version of KnotGuide collects anything new, this page will be updated before that version ships, and the date at the top will tell you when.
