SizeFill: Resize All Images & Image Size — Privacy Policy

Last updated: 11 November 2026

SizeFill is an add-on for Google Docs™ that sets the size of the images in a document: the one you select, or every image at once. This policy says what it does with data, including the Google user data it receives.

What Google user data SizeFill accesses

• The document you use it in (scope documents.currentonly). SizeFill finds the images you select, or every image in the document’s tabs, and reads their width and height and the page’s width and margins. When you click Resize, it sets those images’ width and height. It does not read or change the document’s text, and has no access to your other documents or files.
• Your email address (scope userinfo.email). It is how your purchase is found: SizeFill looks up the Stripe customer with this email and, when you start a checkout, creates one. It is also shown in SizeFill so you can check which Google account is used for your free runs and purchase. Google’s installation screen may also say the add-on can ‘associate you with your personal info on Google’. That is Google’s standard sign-in association; SizeFill does not request, read or store your profile information.
• Sidebars and menus (scope script.container.ui), to show SizeFill inside Docs™.
• Connections to outside services (scope script.external_request), to exactly one: Stripe (api.stripe.com), to check purchases and sell the one-time unlock.

How SizeFill uses that data

• Your images are resized inside Google’s Apps Script. Only their displayed size changes; the pictures themselves are not read, copied, stored or sent anywhere.
• Your settings (your purchase status and your Stripe customer number) are kept in your own Google account’s storage for the add-on, with a mark that the deletion described under PacketFill below has been done.
• Free allowance records, in the same account storage, keep how many of your free runs for several images at once are spent. The latest one adds a random identifier, a one-way fingerprint made from the document’s ID and a random value, its status and its number of images resized, so that a retry is not counted twice. No document content is stored in these records.
• A count of your runs: once SizeFill is on the Marketplace, your account storage counts your resizes, so that after a few it can ask you, once, whether you would review it. It is used for nothing else.
• PacketFill: SizeFill takes the place of PacketFill on the same Google Workspace Marketplace listing. The first time SizeFill opens for your account, everything PacketFill kept in your account’s storage is deleted: its free allowance and generation records, the list of temporary copies it was about to delete, its count of your runs and its billing cache.
• Payments are made on Stripe’s checkout page. Stripe receives your email, card and billing address; SizeFill never sees your card. We can see in Stripe your email, your billing country and your purchase, which we need to provide the service and to account for tax. Stripe’s Privacy Policy applies.

SizeFill uses Google user data only for the features above. It does not sell or rent it, does not use it for advertising, and passes it to no one except as those features need: your email to Stripe. SizeFill has no servers of its own. The contents of your documents are never sent to us or to anyone else. SizeFill uses no analytics service; it counts in its own error log how many accounts reach each usage step described below.

SizeFill does not use Google user data, including data received from Google Workspace™ APIs, to develop, improve or train AI or machine-learning models, generalized or personalized.

SizeFill’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Who SizeFill shares Google user data with

• Stripe (our payment processor, Privacy Policy) receives your email address, to find your purchase and, when you buy, to create your customer record and take the payment. Stripe receives nothing else of your Google user data: no document content.
• Your document never leaves Google’s services.

Nothing else is shared, transferred or disclosed: SizeFill does not sell, rent or trade Google user data, and does not give it to advertisers, data brokers, analytics providers or any other third party. We would disclose it only if the law required us to, and only what it required.

How SizeFill protects that data

• Encryption in transit. Everything SizeFill sends or receives travels over HTTPS (TLS): between your browser and Google, and from Apps Script to Stripe.
• Encryption at rest. Your document, SizeFill’s settings and its error log are stored by Google, which encrypts the data it stores. Your customer record is stored by Stripe, which encrypts it too.
• Access controls. SizeFill runs inside Google’s Apps Script, as you, with only the scopes above and only in the document you open it in. We have no access to your documents or to your settings. Your customer record sits in our Stripe account, which only we can sign in to. SizeFill reaches Stripe with a restricted key that stays on Google’s servers and never reaches your browser.
• Never stored: the contents of your document outside it, your card details, and your Google password or sign-in tokens.
• Errors: when something fails, its error message (such as a Stripe error) goes to SizeFill’s error log in Google Cloud™, which only we can read.
• Usage steps: each of these steps adds one line to the same error log, naming only SizeFill and the step: the sidebar opens, it opens on the Pro offer, Unlock Pro is chosen, images are resized, a resize stops at the free allowance. The line holds no document content, size, email address or file name. Google adds to every line in the log its own key for the account, which does not name you, is used only by SizeFill and changes every 30 days. We use it only to count how many accounts reach each step, and never link it to payments, email addresses or other records.

Keeping and deleting

• The error log, usage steps included, is deleted after 30 days.
• The sizes SizeFill set are part of the document and stay until you change them or delete the document.
• Free allowance records have no automatic expiry; the next counted run replaces the latest one’s record without resetting the count used.
• Your settings and free allowance records stay in your Google account’s storage for SizeFill and contain no document content. Uninstalling SizeFill (Extensions > Add-ons > Manage add-ons) stops it; removing it at https://myaccount.google.com/connections also ends its access to your account, after which nothing reads them.
• What PacketFill made in your Google Drive™ (PDFs, folders and sample templates, and any “PacketFill temporary copy” an interrupted run left) stays there until you delete it: SizeFill has no access to Drive.
• To have your data at Stripe deleted, write to us and we delete your Stripe customer. The records of your payments are kept for five years after the end of the financial year they belong to, as Danish bookkeeping law requires, and deleted after that.
