v0.26.0

Nuevo editor, firma guardada, un diseño más sereno

Desde el 12 de septiembre ha cambiado algo en casi todas las páginas. El editor ahora conoce a las personas y coloca para cada una firma, iniciales y fecha. Las firmas se pueden guardar en la cuenta, la página de estado muestra el avance por persona y quien elimina su cuenta ya no deja sin sus contratos terminados a las demás partes.

  • Un diseño sereno en todas las páginasDiseño

    Superficies blancas, una sola tipografía, líneas finas y un acento en coral. La página de inicio, el editor, la firma, el panel, los ajustes y los correos siguen ahora el mismo diseño. Se han eliminado los efectos en movimiento y los emoji.

  • Editor con personas, firma, iniciales y fechaNuevo

    En «Quién firma» añade a las personas y coloca para cada una firma, iniciales y fecha en el documento. La fecha se rellena con el día de la firma. En «Rellenar» escribe usted mismo un texto, la fecha de hoy o un campo con nombre. El documento se desplaza de forma continua por todas las páginas.

  • Teclado y deshacer en el editorMejora

    Las flechas mueven el campo seleccionado, en pasos grandes con Mayús, y Supr lo elimina. No se pide confirmación: «Deshacer» en la línea de aviso o Cmd+Z (Windows: Ctrl+Z) recupera el campo o la persona.

  • Enlaces personales por correo desde el editorNuevo

    Si indica en el editor la dirección de correo de una persona, esta recibe su propio enlace para firmar al finalizar. El enlace compartido sigue disponible.

  • Página de estado con el avance por personaMejora

    La página de estado muestra primero quién ya ha firmado y quién falta, persona por persona.

  • Guardar la firma en su cuentaNuevo

    Puede guardar una firma en los ajustes o al firmar. El diálogo la ofrece entonces como primera opción. Solo se aplica con un inicio de sesión de hace 15 minutos como máximo. Es voluntaria y se puede eliminar en cualquier momento; los contratos ya firmados no cambian.

  • Firmar con «De qué se trata»Mejora

    La página de firma se ha rehecho. «De qué se trata» en la cabecera abre un breve resumen, creado automáticamente a partir del documento. No sustituye a la lectura y no es asesoramiento jurídico.

  • Cada documento empieza con una subidaMejora

    Usted sube uno o varios PDF, canusign propone campos de firma y usted los revisa en el editor. Las plantillas y el documento en blanco ya no están en la aplicación.

  • Paquetes de 5, 15 y 50 documentosMejora

    El antiguo bono forma ahora parte del contenido del paquete, con los mismos precios. Se factura por documento. El botón de compra lleva directamente al pago y la página de pago indica el contenido junto al precio.

  • Sello y certificadoMejora

    El sello junto a la firma puede llevar un cargo o título. El certificado de auditoría indica la dirección de correo que la persona introduce al firmar. La página de verificación tiene un nuevo diseño y sigue sin requerir cuenta.

  • Eliminar la cuenta conserva los contratos terminados para las demás partesSeguridad

    Antes de eliminar, canusign muestra qué se borra y qué se conserva. Los contratos firmados por completo en los que participan otras personas siguen accesibles para ellas mediante sus enlaces y la página de verificación, sin vínculo con ninguna cuenta, y se eliminan diez años después de la última firma. Una suscripción Pro termina con la eliminación.

  • Privacidad: sin huella del dispositivoSeguridad

    La protección contra cuentas múltiples para el documento gratuito solo comprueba ya la dirección IP y el correo. La cookie con la huella del dispositivo ya no se establece y se elimina en las cuentas existentes. La dirección IP se borra a los siete días.

  • Ayuda reescritaMejora

    Las guías describen el funcionamiento actual, desde la subida y las personas y campos hasta la firma, en los cuatro idiomas.

  • Servidores en Fráncfort, cuatro idiomasInfraestructura

    Las funciones, la base de datos y el almacenamiento de archivos funcionan en Fráncfort. canusign está disponible en alemán, inglés, español y francés, y en alemán y español trata siempre de usted. El italiano, el neerlandés y el portugués se han desactivado; sus direcciones redirigen al inglés.

  • API: cancelar, enlaces personales, registro de solicitudesNuevo

    Los contratos en curso se pueden cancelar a través de la API. Los enlaces personales por persona también existen para contratos creados desde plantillas y a través del servidor MCP. En los ajustes aparece cada solicitud a la API con método, ruta, estado y duración, sin contenido.

  • Documentos largos en el PDF firmadoCorrección

    Los documentos de más de 20 páginas fallaban al generar el PDF firmado. Ahora se unen por partes, y las páginas se generan en paralelo en lugar de una tras otra.

Versiones anteriores, solo en inglés

Las entradas hasta la versión 0.25.0 se escribieron solo en inglés y se muestran aquí sin cambios.

v0.25.0

Proof anyone can check: signature, seal, certificate, verify page

A user wrote that our signature looked like a pasted image, that the audit certificate could have been written in Word, and that nobody gets a decent signature out of a mouse. He was right on all three. Signing now offers typing, drawing and uploading; every signature carries a stamp with the name, the time and the document ID; the finished PDF is built once, timestamped by DigiCert and kept, so Adobe Acrobat reports it as signed and unchanged; and the new audit certificate carries a QR code to a public page where anyone can drop the PDF in and see whether it matches the copy we hold. The document ID is printed on every page, so the proof survives printing.

  • Type, draw or upload a signatureNuevo

    The signing dialog asks for the name first, then offers three tabs. Typed signatures are set in one of four handwriting fonts and rendered in the browser, so the PDF service never needs the font. Drawing runs on a smoothed pen with pressure-like line width on a retina canvas, and the export is cropped to the ink. An uploaded photo or scan of a signature is re-encoded, which strips EXIF and GPS data along the way. On a desktop, typing is the honest recommendation: a mouse produces a scrawl, and that was the complaint.

  • A stamp beside every signatureNuevo

    Each signature sits on a line with a faint guilloche seal behind it and a small table underneath: who signed, the time with its zone, the document ID in groups, and where the proof lives. No IP address, because a forwarded PDF would otherwise carry the address of every signer next to their name. The seal survives a laser printer: a print test showed the first version dissolving into toner dots, so the lines got thicker and the tint stronger.

  • Audit certificate rebuilt, with a QR codeNuevo

    The certificate now looks like a document instead of a memo, and it carries what a third party needs: per signer the signature image, the name they typed, how they signed (typed with the font name, drawn with mouse, finger or pen, or uploaded), the time in UTC and Berlin time, IP address, device, and the SHA-256 of the signature image. Below that the full history with IPs, the SHA-256 of every uploaded original, and a QR code that leads to the verify page. Available in every interface language.

  • A public verify page for any signed PDFNuevo

    canusign.com/verify takes the document ID from the certificate or from the footer of a printout and answers three questions: does the document exist, is it fully signed, and who signed it (initials only). Drop the PDF onto the page and the browser computes its fingerprint locally and compares it with the copy we hold. The file never leaves the computer, and no account is needed.

  • One signed PDF, timestamped and keptMejora

    The signed PDF used to be rebuilt on every download, which meant a fingerprint of it was worthless: every copy differed. It is now built once when the last signature arrives, timestamped against DigiCert per RFC 3161 with the validation data Acrobat needs for the long term, and stored. Every download returns exactly those bytes, and Adobe Acrobat and the free Reader report "signed and all signatures are valid". If the timestamp service is unreachable the download still works, just without the timestamp, and the next one tries again.

  • The API hands out the proof as wellMejora

    Contract responses and the contract.completed webhook now carry publicId and verifyUrl, and GET /contracts/:id also returns finalPdf.sha256, the fingerprint of the stored PDF. An integration can put the verify link into its own interface and check the file it downloaded without trusting the download.

  • A signing link no longer exposes IP addressesSeguridad

    Anyone holding the link could read the IP address and user agent of every signer, plus the internal payment data of the contract. Those fields now reach the owner only; everyone else sees the contract, the signatures and a reduced history.

v0.24.0

Checkout rebuilt on Stripe Checkout Sessions

The whole payment path now runs on a single Stripe Checkout Session, and prices live in Stripe rather than in the code. That sounds like plumbing, and mostly it is, but it fixes things customers could feel: a visitor in Britain used to read pounds on the pricing page and be charged euros, because the currency was guessed from their country while the charge came from a separate table. Stripe decides the currency now, from where the customer actually is, and offers the payment methods that go with it. Every purchase gets a confirmation mail that doubles as the way into the account, so paying as a guest no longer ends in a dead end. Buying credits, buying Pro and cancelling Pro all run through one flow instead of five separate routes with their own price lists.

  • Every purchase gets a confirmation mail with a sign-in linkNuevo

    One mail, not two: the receipt required for a distance contract and the way into your account are the same message. It states what was bought, what was charged and in which currency, links to the Stripe receipt, and carries a link that signs you in on any device for seven days. For anyone who paid without an account it is the way to the credits they just bought, so the success screen leads with the inbox and shows the address back for checking, instead of burying it under a payment confirmation.

  • The currency comes from Stripe, not from a guessMejora

    Prices are held in Stripe with their own amounts for the euro, dollar, pound and Singapore dollar markets; everywhere else Stripe converts. The pay button always shows what will actually be charged, including currencies without decimals, where the old code would have been off by a factor of a hundred. Before a checkout is open the pages state the integration currency, because until the payment form loads nobody knows where the customer is.

  • Pro is bought and managed in one placeMejora

    Buying Pro runs through the same checkout as everything else and lands in Settings, and Billing & payments now opens the account that actually holds the subscription and the invoices. Cancelling keeps Pro until the end of the paid month and then steps the plan back down on its own.

  • Payments reach the account that made themCorrección

    A signed-in buyer is now recognised as themselves even when the payment carries a different address, which wallets routinely do. Previously a paid credit could land on a second, newly created account while the buyer watched their own balance stay empty.

  • Revenue is recorded per purchase, with its currencyInfraestructura

    Each completed payment writes a row with the amount and the currency it was charged in. Reporting no longer has to ask Stripe, which answers for an account shared with another product, and revenue is never converted at a rate nobody was charged at.

v0.23.0

Pay-per-signature positioning + duplicate-for-new-signer

Sharpened the landing experience around the pay-per-signature wedge (no subscription, no account for signers, eIDAS-compliant) after a competitive audit confirmed that the real competition is free-tier-then-upsell tools like DigiSigner and BoldSign, not enterprise DocuSign. The pricing line on the landing page now anchors to the actual single-signature price (€1.49) instead of the cheapest-per-credit bulk-discount floor, which was misleading first-time visitors. Two new in-product nudges surface the 'your credit covers it' framing exactly where the data showed users abandoning: above the Continue button in the editor, and as a re-engagement banner on the dashboard for users with credits and a finished draft. The new duplicate-for-new-signer action turns a one-time signed contract into the starting point for the next one, which is how the top power users actually use the product (property managers sending the same lease to multiple tenants, B2B onboardings, repeating coaching agreements). Help and contact also got a clear home inside Settings instead of being hidden behind the generic Feedback link.

  • Duplicate a contract for a new signerNuevo

    Any contract with a document now has a "Duplicate for new signer" action in the dashboard menu. It clones the source contract, including its uploaded PDF/text pages and field placements, as a fresh draft with a new token and "(copy)" appended to the title, ready to send to the next tenant, client, or counterparty without re-uploading and re-placing signature fields. This is the path most of our recurring users were taking manually (re-upload, re-place fields each time); now it is one click.

  • Help & contact section in SettingsNuevo

    Logged-in users had no obvious path to get in touch from inside the app: the Feedback menu item buried the contact form behind a tab. Settings now has a dedicated Help & contact section with three entries: "Send us a message" (deep-links to /feedback?tab=contact, the contact form opens immediately), a direct mailto:contact@canusign.com fallback for users who prefer their own mail client, and "Request a feature" pointing at the public feature-voting list.

  • Cost preview above the Continue button in the editorNuevo

    Once a user has placed at least one signature field, the editor now shows a one-line cost preview directly above the Continue button so the price impact is visible before the user clicks through to /payment. Logged-in users with credits see "Free, your credit covers it" (with available balance); logged-in users at zero balance see "€1.49, one credit required"; guests see "First signature free, no subscription". Many users left at this step without realising their credit already covered the cost.

  • Re-engagement banner for stuck drafts on the dashboardNuevo

    Users with at least one draft contract that already has a document attached and credits in their balance now see a prominent mint/coral banner above the contract list: "You have N drafts ready to send, your credit covers it." Clicking jumps straight into the editor for the first stuck draft. Targets users who got their free signup credit and uploaded a PDF but never finalised.

  • Landing hero rewritten around the no-subscription wedgeMejora

    New hero copy:"Sign PDFs. No subscription." with subtitle "Need a signature today? Pay €1.49 once, no trial, no account for your signers. eIDAS-compliant, built for the EU." Replaces the previous neutral "Sign PDFs Online / Upload any PDF, add signatures..." framing. The new copy explicitly targets the real competitive set, free-tier tools that pressure users into subscriptions after the trial, rather than enterprise e-signature players that share none of our pay-per-use audience.

  • Landing page price anchor: €1.49 per signature, not a bulk price per creditCorrección

    The landing page advertised the price per credit of the largest pack, which was the cheapest-per-credit price floor when buying the largest bulk pack, and in the wrong currency. First-time visitors then hit the Single pack at €1.49 at checkout and felt baited. The label now anchors to the actual single-signature price they will see at checkout (€1.49 in EUR; geo-currency adapted), and the wording shifted from "per credit" to "per signature" in every locale so the same noun is used end-to-end from landing, editor and checkout.

v0.22.0

Passkey login and Google OAuth: sign-in rebuilt

Swapped the entire auth stack from NextAuth v5 to Better Auth and put the new capabilities in front of users. /login now offers three sign-in methods: magic link (email), passkey (Touch ID / Face ID / Windows Hello via WebAuthn conditional UI), and Google OAuth. /settings/security is the new home for managing passkeys and listing active sessions, with one-click revoke per device or sign-out-everywhere-else. The post-payment success card no longer bleeds packs and promo banners through; once the credit is purchased, only the magic-link confirmation remains visible.

  • Passkey login with conditional UINuevo

    Email field on /login carries autocomplete="username webauthn" so browsers surface saved passkeys directly in the autofill dropdown. An explicit "Sign in with Passkey" button handles the fallback. Per-user passkey management at /settings/security (add, rename, delete) lists every credential with the device type and registration date.

  • Google OAuth sign-inNuevo

    Continue-with-Google button on /login wired to Google Cloud OAuth. Gated by NEXT_PUBLIC_GOOGLE_LOGIN_ENABLED so previews without credentials still build cleanly.

  • Active session list + revokeNuevo

    /settings/security lists every active session with the browser/OS guess, IP, and sign-in date. "Current" badge on the active session, per-row revoke, plus "Sign out other devices" when more than one session exists.

  • Cleaner post-payment success screenMejora

    Pack selector, promo banner, trust badges, comparison hint, and Sign-up-free CTA all collapse once payment succeeds. Only the magic-link confirmation card stays visible, so guests see one obvious next step instead of a scroll of unrelated UI.

v0.20.0

Locale-aware blog content

Blog articles outside English now start from the legal framework of their market instead of US law.

  • Blog content now respects local jurisdictionsMejora

    Articles for non-English locales now reference the actual local legal framework (eIDAS, RGPD, BGB, Codice Civile, KEP, 電子署名法) instead of US-only terms. Geo-locked topics (HIPAA, IRS Form 8879, ABA Model Rules) are blocked from generating in non-US locales.

v0.19.0

Link previews and payment fixes

A tightened Open Graph and manifest setup, so links shared on social platforms render with the proper preview, theme color and Apple web-app metadata, plus small fixes on the payment page.

  • Manifest, theme color & Apple web-app metadataDiseño

    Proper PWA manifest, theme color tokens for browser chrome, and Apple-specific metadata so the site behaves like a native install on iOS Safari "Add to Home Screen".

  • Browser-back from payment now lands in editorCorrección

    Hitting the browser back button after a Stripe redirect used to throw users into a broken state. Now it properly returns to the editor with the document still loaded.

  • Pricing copy reflects credit-pack modelCorrección

    Removed legacy "€1/document" claims from marketing pages. Pricing now matches the actual credit-pack tiers (Single €1.49, Starter €4.90, Popular €9.90, Business €24.90, Pro €15/mo).

v0.18.0

Credit system, accounts & anti-abuse

The biggest change since launch: moved from per-document Stripe checkout to a credit pack system with user accounts, magic-link login, and a personal dashboard. New users get one free credit on signup, then buy packs with bonus credits stacked on top. Plus a referral program, anti-abuse system, and exit-intent conversion optimization.

  • Credit packs with bonus tiersNuevo

    Buy credits in bundles: Single (€1.49), Starter (€4.90 with +1 bonus), Popular (€9.90 with +5 bonus), Business (€24.90 with +15 bonus), or Pro at €15/month for unlimited use. Bonus credits highlighted in green throughout the UI.

  • User accounts & dashboardNuevo

    Magic-link login via email (no passwords). Personal dashboard shows your documents, credit balance, and credit history. Guest documents created before signup get migrated to your account on first login.

  • Inline Stripe paymentNuevo

    No more redirect to Stripe Checkout. Card form is embedded directly on the payment page so you stay in context. Single pack pre-selected for one-click purchases. Replaced in 0.24.0 by Stripe Checkout Sessions.

  • Referral programNuevo

    Each account has a 6-character referral code. Invite a friend and you both get a free credit when they sign up. Email notification when someone redeems your link.

  • Anti-abuse systemSeguridad

    Disposable email domains blocked at signup (~100 domains covered). IP rate limit: max 3 bonus-credit signups per IP per 24h. Browser fingerprint plus signup-fingerprint persistence prevent bonus farming via account deletion + re-registration. The browser fingerprint was dropped on 23 September 2026; the check now runs on IP address and email only.

  • Avatar dropdown & credit badgeMejora

    New header with avatar dropdown (Settings / Feedback / Logout) and a credit badge that turns mint when you have credits, gray when at zero. Click the badge to jump straight to your settings.

  • Conversion optimizationMejora

    Trust badges (SSL, eIDAS, GDPR), social proof on the homepage, exit-intent popup with discount, and a sticky blog CTA bar that follows you while reading articles.

v0.17.0

Better signing flow & mobile polish

The signing experience got a major redesign with an integrated document header, page tabs with status icons, and proper mobile gestures. Loading states feel responsive, navigation is unified across all step types, and pinch-to-zoom works the way users expect.

  • Integrated document header during signingMejora

    Status, page counter, page tabs and the action button are now combined into one header on top of the document. Page tabs are numbered and show a pen icon for unsigned pages, a check for signed ones, colored to match each signer.

  • Pinch-to-zoom on mobileMejora

    Native pinch gesture support plus dedicated zoom controls underneath the document. Touch targets for navigation arrows enlarged for fingers.

  • Unified navigation for every step typeMejora

    Same navigation pattern whether the document is a contract, uploaded PDF, text, or image. Reduces cognitive load and code surface.

  • Signing loader overlayNuevo

    Visible loading state during the signing API call, so there is no more wondering if the click was registered.

  • "Partially signed" statusNuevo

    Documents with at least one signature but not all show as "Partially signed" in the dashboard, with a clear count of remaining signers.
