Privacy Policy

Last updated October 24, 2026

VialVine (“VialVine,” “we,” “us”) is a record-keeping app for vials, routines and entries. This policy explains what information we handle, why, and the choices you have. We wrote it to be read, not skimmed past.

The short version

  • On the Free plan, your records stay on your device. We don’t receive them.
  • If you create an account or use Pro, we store what’s needed to run it: your email, your synced records and COA files, and your subscription status.
  • We don’t sell your information, we don’t show ads, and we don’t share your records with anyone unless you choose to (for example, sharing a vial with your Companion).
  • You can delete your account and cloud data at any time in Settings.

Information you keep in VialVine

Your records can include compounds, vials and other containers, amounts, routines, entries, body sites, weight, notes, purchase details and Certificates of Analysis (COAs). Some of this may be considered health information. You decide what to record.

  • Free, without an account: records are stored only in your browser on your device. They are not sent to us. If you clear your browser data or lose the device, they’re gone unless you saved a backup.
  • With an account or Pro: to sync between your devices, your records and COA files are stored on our cloud provider (Cloudflare). They are encrypted in transit and at rest by the provider. Only your signed-in account can read them through the app. This is standard cloud security, not end-to-end encryption.
  • Backups: backup files you save are encrypted with a password you choose and stay wherever you put them.

Information we collect to run the service

  • Email address, to sign you in with a one-time code or link and to send account notices (for example, a sign-in code or a note before cloud data is deleted). Emails never include your records.
  • Subscription details. Payments are handled by Stripe. We receive your plan, status and renewal date. We never see or store your full card number.
  • Error reports. If the app hits an error, it may send us technical details: the error message, the page, the app version and your browser type. Error reports never include your records, notes or amounts.
  • Feedback you send us, and your email if you include it.
  • Site analytics. We use Cloudflare Web Analytics to count visits and see which pages are used. It doesn’t use cookies and doesn’t track you across sites.

Sharing you choose

  • Companion: if you share a vial with your Companion, they can see that vial, what’s left and their own entries on it. They don’t see your other records, notes or weight. Shared supplies show the supply and what’s left.
  • Public COA links: if you make a label QR code that opens a COA, anyone with that link can view that COA file. You can turn the link off at any time.

Who helps us run VialVine

We use a small number of service providers, only for the purposes above: Cloudflare (hosting, storage, analytics), Stripe (payments) and Resend (sign-in and account emails). They process information on our behalf and aren’t allowed to use it for their own purposes. We may disclose information if required by law, or to protect the rights and safety of our users or VialVine.

How long we keep information

  • Records on your device stay until you delete them or clear your browser data.
  • Cloud records are kept while you have Pro. If Pro ends, we keep your cloud copy for 90 days so you can come back without losing anything, then delete it. We email you before that happens.
  • When you delete your account, we delete your cloud records, COA files and sharing links. Payment records are kept by Stripe as required for tax and accounting.
  • Error reports and feedback are kept as long as needed to fix problems and improve the app.

Your choices and rights

  • Access and export: save a backup of all your records at any time in Settings.
  • Delete: remove sample data, individual records or your whole account in Settings.
  • Withdraw consent: stop using cloud features or delete your account at any time.
  • Depending on where you live (for example, Washington, California or other states with consumer health or privacy laws), you may have additional rights to know, access, correct or delete information, and to appeal a decision. Email us and we’ll respond within the time the law requires.

Security

We use encrypted connections, sign-in codes instead of passwords, and access controls so only your account can read your cloud records. No system is perfect; if we learn of a breach affecting your information, we’ll notify you as the law requires.

Not for children

VialVine is for adults 18 and over. We don’t knowingly collect information from anyone under 18.

Changes

If we change this policy, we’ll update the date above, and for significant changes we’ll let you know in the app or by email.
