Terms and provider
Effective 27 October 2026.
Yolleg Ltd · Company 10455920 · Registered office: 71–75 Shelton Street, London, England WC2H 9JQ, United Kingdom · [email protected].
Product and scope
Customer access to existing calibration PDFs and manually sourced equipment due dates. A named matching-email account is required for the portal. Unknown due dates remain explicit and produce a review flag for Active equipment. Retired equipment stays in history and is excluded from current due alerts. No certificate generation, measurement interpretation, accreditation verification, default calibration interval or automatic recipient email. One customer, five equipment records and eight certificate versions are free. Two frozen reviews, three imports and three original PDFs / 10 MB included. One active named customer grant. Business Pro: 100 customers, 1,000 equipment versions, 5,000 certificate versions, 500 reviews and four staff. 100 PDFs / 250 MB; every retained original counts. Up to 100 active named customer grants.
Accounts and staff
Adults aged 18+ acting with authority for the business. Each person signs in with their own email. The owner controls billing, business scope, membership and frozen reviewed packs; editors edit operational records, including decisions; viewers read/export. Pro includes owner plus four staff. In-app invitations use a matching email and expire after seven days; no invitation email is sent. Staff access ends when removed or the owner lacks active Pro. Do not share account links.
Business Pro and payment
Business Pro costs £19.99 every month or £199.90 every year, selected before Checkout. No free trial. Payment starts at purchase; automatic renewal continues until cancelled. Annual payment is charged in full. Prices include applicable tax. GBP billing; your bank may convert currency. Native apps and purchases are separate.
Workflow and limitations
Each certificate belongs to equipment already assigned to the customer. Only owners publish or revoke certificate versions; an earlier certificate remains privately retained. Publication is the operator’s review, not validation of calibration results or accreditation. Customer portal lists show only current Published certificate versions for the granted customer; every PDF download rechecks the signed-in email, owner, customer, active grant and current publication state. Revocation blocks future downloads immediately but cannot retrieve copies already downloaded. Due dates are explicitly entered from the source, not inferred from a monthly review schedule. Calendar exports contain customer/equipment references; share them carefully.
Storage and retained records
16 MB of structured records per owner workspace. Revisions, imports and frozen reviews count towards capacity. Owner read/export remains available after expiry; edits stop if retained counts exceed free limits. Customer portal access requires active Pro or all retained records and active grants within free capacity; the owner retains read/export after expiry. PDF originals: 5 MB per file, free 3 files/10 MB, Pro 100 files/250 MB. Only the owner removes unused originals; referenced files are protected. JSON exports retain record/review metadata but exclude PDF bytes; download originals separately. External references are not fetched or archived. Format checks do not verify contents; use a trusted local reader. Keep exports and required originals securely. After expiry, the owner retains read/export access while the service is available; new operational edits are locked if retained counts exceed free capacity. Erasing records does not cancel billing; cancellation does not erase records. Account deletion through support. Perpetual availability, recovery or a statutory archive is not promised.
Cancellation and withdrawal
Cancel renewal in the secure Stripe cancellation portal, through the declaration form or at [email protected]. Access lasts to the paid period end shown by Stripe. We offer a full refund of the first payment when withdrawal is requested within 14 days of that payment, including after use. Immediate access does not waive that offer. Supply your name, payment email and order reference or approximate date/plan; never card details or sign-in tokens. Acknowledgment of a request is not completed cancellation or refund. Mandatory consumer rights remain.
Availability and rights
Outages may interrupt work. Check and approve outputs before real decisions. Nothing excludes liability that cannot lawfully be excluded. England and Wales law applies subject to mandatory local protections.
