What do you collect?
- Calculator inputs: nothing. Plans are calculated on your device. Share links carry your inputs in the web address, so only share them with people you trust.
- "Email me my plan + reminders": your email address, the link to your plan, the route (for example "Denver → London") and your head-start, departure and arrival dates. Nothing else.
- Page views: counted with Cloudflare Web Analytics, which uses no cookies and doesn't build a profile of you.
- Affiliate link clicks: counted without cookies (which link and which page, plus country). See the affiliate disclosure.
Why do you collect it?
Only to send what you asked for: one email with your plan link right away, then 3 reminders (the morning your head start begins, travel day and your first morning after landing). We may add you to occasional jet lag tips only if you opt in separately.
Who handles it?
- Kit (kit.com): our email provider stores your email, plan link and trip dates and sends the emails.
- Cloudflare: hosts this site and holds a reminder queue (your email and the reminder times) until each reminder is sent, then deletes it.
How long do you keep it?
Reminder queue entries are deleted when the reminder goes out (and automatically within 7 days after). Your Kit record stays until you unsubscribe and ask us to delete it.
How do I unsubscribe or delete my data?
- Click "unsubscribe" at the bottom of any email. No more emails, effective immediately.
- To delete your record, reply to any of our emails and ask. We'll confirm when it's done.
Children
The site is for parents and caregivers. The email form is for adults; please don't let children sign up. We don't knowingly collect personal information from children under 13.
Changes
If this policy changes, we'll update the date at the top of this page.
Frequently asked questions
Do you sell my email address?
No. We never sell, rent or share your email for anyone else's marketing.
How do I unsubscribe?
Click the unsubscribe link at the bottom of any email. It takes one click, and you will not get any more reminders.
How do I delete my data?
Unsubscribe, then reply to any of our emails asking us to delete your record. We delete it from our email provider and the reminder queue.
Does the calculator send my trip details to you?
No. The calculator runs in your browser. Trip details only reach us if you submit the "Email me my plan" form.
