Licence renewal

Myeline licences have a maximum duration of 12 months. This page covers the renewal cycle and recovery procedures in case of incident.

Why max 12 months?

Sovereign air-gap deployments cannot be revoked instantly (no network connection to push a revocation list). Short expirations are the only practical lever to stop usage if a customer doesn't renew. That's why the licence generator refuses durations > 12 months.

D-30: yellow alert

A yellow banner appears on all admin pages:

Myeline licence expires on 6 May 2027 (15 days remaining). Without renewal, the app will refuse to start after that date. Contact hello@myeline.io to receive your new key.

Logs include a warning at boot:

WARNING  app.license  ⚠️  License expires in 15 days (on 2027-05-06T23:59:59Z).

D-7: red alert

The banner turns red (alert-danger). It's your last safety net to plan the renewal.

D0: action

  1. Commercial side: pay the renewal invoice received by email
  2. Technical side: receive the new MYE-... key by email (secure channel)
  3. On the server: 
    # Save the previous value (just in case)
cp .env .env.backup-$(date +%Y%m%d)
# Edit .env
nano .env
# → Replace the LICENSE_KEY=MYE-... line with the new value
# Restart
podman-compose restart web
# ~30 s downtime
  4. Verify: https://your-domain/license-info must show the new expiry date

No data loss — the database and volumes are untouched.

Emergency procedure: expired licence

If you missed the alerts and the app refuses to start:

podman-compose logs web | tail -20
# → ERROR ... LicenseError: license expired on 2027-05-06T23:59:59Z

Same as above. If the email channel works, you're back up in ~5 min after receipt.

Option 2 (absolute emergency): dev-mode workaround

Strictly temporary use

This procedure disables the licence check by setting FLASK_ENV=development. It's a 15-minute emergency patch at most, never a sustainable solution. Your contractual licence terms require a valid licence in production.

# Edit .env
nano .env
# Change: FLASK_ENV=production → FLASK_ENV=development
podman-compose restart web

The app starts in "unlicensed dev" mode with a loud warning in the logs. As soon as you have the new key, restore FLASK_ENV=production + the new licence and restart.

Option 3: direct contact

If the email channel is broken (e.g. your Brevo is down + air-gap):

  • Phone hello@myeline.io
  • Exchange via Signal or another secure channel
  • We can transfer the key as a signed file on a temporary share

Recovering a corrupted public key

Symptom: the app refuses to start with:

LicenseError: public key not found at app/myeline_license_pubkey.pem

or:

RevocationListError: revocation list signature invalid — was tampered

Possible causes: disk corruption, bad Git operation, docker volume incorrectly mounted.

Fix

cd /path/to/myeline
git log --oneline app/myeline_license_pubkey.pem
# verify the file is committed
git checkout HEAD -- app/myeline_license_pubkey.pem app/myeline_license_revoked.json
podman-compose restart web

If you can't pull (true air-gap), ask us for the myeline_license_pubkey.pem file by email (it's public, no security risk). Drop it at app/myeline_license_pubkey.pem and restart.

Why no auto-renewal?

This is intentional:

  • Sovereign air-gap: technically impossible (no reachable API to ping a renewal service)
  • Hybrid: technically possible but we prefer a human touchpoint at each renewal — it's the chance to review usage, adjust quotas, flag pricing or feature changes

Renew before expiry

Recommended: kick off renewal at D-45 for a comfortable margin. Simple email to hello@myeline.io:

Hi,

Myeline licence renewal for ACME Corp (sovereign), expires 2027-05-06. Same parameters for another 12 months.

Thanks.
