Privacy Policy
Last updated: June 13, 2026
Overview
TailCheck ("we," "us," or "our") operates the website at tailcheck.me and the TailCheck mobile application (collectively, the "Service"). This Privacy Policy explains what information we collect, why we collect it, and how we handle it.
The short version: we collect only what is strictly necessary to provide the Service. We use privacy-safe first-party product analytics, we do not sell your information, and we never share it for anyone else's benefit.
Your use of the Service is also governed by our Terms of Service.
Information We Collect
Account Information
When you create an account, we collect your email address and, optionally, your full name. This information is used to identify your account, communicate with you about the Service (e.g., password resets, critical service updates), and — unless you opt out — send occasional product news and tips. We do not use it for profiling or targeted advertising. You can opt out of non-essential marketing emails at any time from your account settings or the unsubscribe link in those emails; essential account emails are always sent.
Aircraft Logbook Data
When you upload logbook documents (PDFs or photographs), we store and process those files to provide the core functionality of the Service — digitizing maintenance records, generating timelines, and producing compliance reports. Delivering these features involves automated processing by the service providers described under Data Sharing below. This data belongs to you. We access it only to operate the Service on your behalf.
Photographs (Mobile App)
The TailCheck mobile application may request access to your device's camera to photograph logbook pages for upload. Photos are transmitted directly to our servers for processing and are not stored on your device beyond the upload session. We do not access your photo library or any images other than those you explicitly capture through the app.
Billing Information
When you purchase a subscription, payments are processed by our third-party payment processor, Stripe. We never see or store your full card number — your payment details are handled entirely by Stripe under its own privacy policy. We store only the information needed to manage your subscription, such as your Stripe customer and subscription identifiers, your subscription status, which aircraft a subscription applies to, and a record of your purchases for billing and support.
Product Analytics and Information We Do Not Collect
We use privacy-safe product analytics to understand which public pages are useful and whether visitors successfully start an account. This includes a first-party anonymous visitor ID, page paths, referral source, campaign parameters, and signup actions. If you later submit your email or sign in, we may link that earlier anonymous activity to your account so we can understand what helped you find TailCheck.
We also want to be explicit about what we do not do:
- We do not use fingerprinting scripts or try to identify you across unrelated websites.
- We do not sell, rent, license, or trade your analytics data.
- We do not use your logbook data for targeted advertising.
- We do not use third-party cookies. Cookies or local storage we set are first-party and used for authentication, attribution, or product analytics.
How We Use Your Information
Your information is used exclusively to:
- Authenticate your identity and maintain your session.
- Process and store your uploaded logbook documents.
- Generate reports, timelines, and compliance analyses that you request.
- Manage your subscriptions, process payments, and provide billing support.
- Send transactional emails directly related to your use of the Service (e.g., password reset links).
- Send occasional product news, tips, and announcements — which you can opt out of at any time, after which you will still receive essential account emails.
That is the complete list. There are no other uses.
Data Sharing
We do not sell, rent, license, or trade your personal information or logbook data — not now, not ever. The only third parties that ever touch your data are the service providers we rely on to operate the Service, and they act strictly on our instructions, never for their own purposes.
You — and only you — decide whether to share your aircraft data. The Service lets you share an aircraft with specific registered users you choose, or publish a public profile or report. Nothing is shared with another user or made public unless you turn it on, and you can revoke that access at any time. We never share your data with other users or the public on your behalf.
The service providers we use fall into two categories: (a) infrastructure providers, such as cloud hosting and database services, that store your data; and (b) automated processing and analysis providers that we use to digitize your logbooks, extract information, and generate reports. Delivering those features requires transmitting the contents of your uploaded documents to these providers. They process your data only to return results to us, are contractually restricted from using it to train their own models or for any other purpose, and retain it only as long as needed to complete processing (plus any limited period required for security and abuse prevention). We may also disclose information where required by law pursuant to valid legal process. Payment information is handled separately by Stripe, as described above.
To send account and product emails, we use Customer.io, an email service provider. We share your email address, name, and limited account attributes (such as your subscription status, product-usage milestones, and first-party attribution data) with Customer.io so it can deliver these emails on our behalf, honor your email preferences, and help us understand account lifecycle journeys. Customer.io processes this data under our instructions and its own privacy policy, and we never share your logbook documents with it.
Data Storage and Security
Your data is stored on Amazon Web Services (AWS) infrastructure in the United States. We use encryption in transit (TLS) and at rest. Access to production systems is restricted to authorized personnel through multi-factor authentication and audit logging.
Data Retention and Deletion
We retain your account information and uploaded documents for as long as your account is active. You may request deletion of your account and all associated data at any time by contacting us at support@tailcheck.me. Upon request, we will permanently delete your account, personal information, and all uploaded documents within 30 days.
Children's Privacy
The Service is not directed at children under 13. We do not knowingly collect information from children under 13. If we learn that we have collected personal information from a child under 13, we will delete it promptly.
Changes to This Policy
We may update this Privacy Policy from time to time. If we make material changes, we will notify you by email or through a prominent notice on the Service. The "Last updated" date at the top of this page indicates when the policy was last revised.
