Privacy Policy
Last updated October 13, 2026
PigeonTrail is run by Signal Harbor Technologies LLC ("we", "us"). This policy covers two groups of people: sellers who use PigeonTrail, and buyers whose letters sellers track with it.
If you got an email or a tracking link from PigeonTrail
A seller you ordered from uses PigeonTrail to mail your order as a tracked letter. The seller collected your information when you ordered and is responsible for how they collect it; we act on their instructions. They gave us your name, your mailing address and, if they had it, your email address. We use it only to check the address, print the barcode, follow the letter through USPS and send you the updates the seller turned on. We do not sell it, use it for advertising or send you anything else. Every email has a link to stop PigeonTrail emails to your address from every seller. For anything about your order itself, contact the seller.
What we collect
- From sellers: your email address, your shop settings (shop name, return address, reply address, which buyer emails to send), and your plan and credit history. Payment details are collected by Stripe; we receive only what Stripe shares with us, such as the last four digits of the card and the billing country.
- About orders and buyers: what a seller uploads or types in: order number, buyer name, mailing address, buyer email if included, and order value if included.
- About letters: the barcode we printed for each letter and the scan records USPS sends us for it: time, operation and the city and state of the mail facility.
- From every visit: IP address, browser type and request logs, used for security and to fix problems.
Cookies and browser storage
We set one cookie, to keep you signed in. The app remembers which envelope or label you print on in your browser's storage. We use no advertising or analytics cookies and no tracking pixels in our emails. Because we do not track you across sites, nothing changes when your browser sends a Do Not Track signal.
Who we share it with
Only the companies that run parts of PigeonTrail for us, and only what each needs:
- Amazon Web Services, which hosts the service and its database.
- Our email provider, Amazon SES, which delivers the emails we send. Open and click tracking is off.
- Stripe, which processes payments.
- ZIP-Codes.com and Geocodio, which receive a delivery address (never the name or email) to look up its ZIP+4.
- The United States Postal Service, which sees your letter like any mail and sends us its scans.
- Hostinger, which hosts our support mailbox when you write to us.
We may also share information when the law requires it, to protect people from harm or fraud, or as part of selling or merging the business, in which case this policy keeps applying to it. We do not sell personal information.
How long we keep it
- Orders, letters, their scans and the emails sent about them: deleted 400 days after the letter was made.
- Checked addresses (without names): deleted after 180 days.
- Raw USPS scan files and scans we could not match to a letter: deleted after 120 days.
- Request logs: 30 days.
- Your account and settings: until you close the account. Payment records are kept as long as tax law requires.
- Addresses that asked not to get our emails, bounced or complained: kept, so that request keeps working.
Your choices and rights
Wherever you live, you can ask us what we hold about you, ask us to correct it, or ask us to delete it, by writing to support@pigeontrail.com. Buyers can also ask the seller to remove their order. We answer within 30 days. Some laws, such as California's, give you further rights, and we honor them.
Security
Information is encrypted in transit and at rest. Sign in links and sessions are stored only as one way hashes, links expire in 15 minutes and work once, and access to production systems is limited to the people who run PigeonTrail.
Children
PigeonTrail is for businesses and adults. We do not knowingly collect information from children under 13.
Where information is
We store and process information in the United States.
Changes
If we change this policy in a way that matters, we will update the date above and email account owners before the change takes effect.
