Privacy Policy

Last updated: September 28, 2026

The short version: tdy runs entirely on your own devices: your Mac, iPhone and iPad. There is no account, no analytics, no advertising, and no tracking. Your clipboard is processed locally and is never sent to us. tdy only touches the network for the four specific, limited purposes described below, and even then it never sends us anything that identifies you.

What stays on your device

• Your clipboard. When you copy a link, tdy reads it, rewrites it, and writes the clean version back, all on your device. Copied content is never transmitted to tdy.
• Your settings. Toggles, per-provider choices, custom proxies, and excluded apps are stored on your device. If you keep iCloud enabled, tdy syncs these settings across your own devices through your personal iCloud account (see “iCloud” below). They are not sent to us.
• Your history. tdy keeps a list of the last 20 links it cleaned. Only the link is kept, before and after cleaning, never the rest of the text you copied. A link cleaned with the keyboard shortcut from an excluded app is not kept at all. How long the list lives is your choice under Keep recent links in Settings: Until tdy quits holds it in memory only; On this Mac (on iPhone and iPad, On this device) writes it to the device; On all your devices also carries it between your own devices through your personal iCloud account (see “iCloud” below). The default is On all your devices, and the choice applies to all your devices at once. The list is never sent to us. Remove and Clear take rows off every device.
• Your activity. tdy counts what it does, per day: how many links it cleaned, which platforms it swapped them to, the names of the tracking parameters it removed (such as utm_source), how many characters that took out, and the hour of the day. These are numbers only, never the links or the pages they point to. Each device keeps its own counts and, if iCloud is enabled, puts them in your personal iCloud account (the last three months day by day, older months as one total each), so Activity, the widgets and the year review add up all your devices. To keep one device’s counts apart from another’s, each device labels its entry with a short code it makes itself from a scrambled (hashed) form of its hardware identifier. The code stays in your iCloud account and is never sent to us. Reset activity sets every count back to zero on all your devices. The widgets read a small file of this week’s numbers that the app writes on the same device. The year review image is made on your device and goes only where you choose to share it.

When tdy uses the network

tdy makes outbound network requests only in these cases:

• Rule updates. Periodically, tdy downloads its provider list (which proxy to use for each platform, tracking parameters to strip, etc.) from edge.tdy.app. This request sends no personal data, only a rotating, non-identifying access token. Like any web request it includes your IP address at the network layer; we do not log it to a profile or associate it with you.
• Link previews (optional). When “Show link previews” is enabled, tdy fetches public page metadata (title/description) for a rewritten link so it can show you a preview. This contacts the link’s host or its embed proxy with that URL. You can turn this off in Settings.
• Short-link resolving (optional, off by default). When enabled, tdy requests a copied short link (e.g. a bit.ly URL) to follow its redirects to the real destination. This contacts the shortener with that URL. You can leave it off.
• Share-link resolution. Some platform links hide their destination (reddit’s /s/ shares and bare /comments/ permalinks, TikTok’s /t/, Facebook’s /share/). tdy resolves these against the platform (or its embed fixer) so the link can be fixed. The request carries only the link itself and is part of normal operation.

In the optional cases, the request goes directly from your device to the relevant website or proxy, not through tdy’s servers.

What tdy never does

• No account, login, or email required.
• No analytics, telemetry, crash trackers, or advertising SDKs.
• No selling, sharing, or brokering of data. There is no data to sell.
• No logging of your clipboard, your links, or your usage on our servers.

iCloud

If iCloud is enabled, tdy uses Apple’s iCloud key-value store to keep three things in sync across your own devices: your settings; the activity counts described above; and, when Keep recent links is set to On all your devices, the recent list. This data is handled by Apple under Apple’s Privacy Policy; tdy has no access to your iCloud account and receives none of it. To keep the list off iCloud but still sync settings, choose On this Mac or Until tdy quits. To stop all syncing, sign out of iCloud or turn off iCloud for apps in System Settings.

Third-party proxies

tdy rewrites links to community-run embed proxies (for example fixupx.com). When you paste and open such a link, you are visiting that third party’s service, which has its own privacy practices. tdy is not affiliated with these services and does not control them.

Children

tdy is a general-purpose utility and is not directed at children under 13. It collects no personal information from anyone.

Changes

If this policy changes, we’ll update the date above and post the new version here. Material changes will be noted in the app’s release notes.
