Privacy Policy

Privacy Policy for Skyfield Google Workspace Add-ons

Introduction

We take the privacy of our users very seriously. We have implemented safeguards to ensure your data remains confidential. We never sell your data, and we share it only with the service providers we need to run Skyfield, or where the law requires it.

Data Storage Notice

We do not store your Google files (emails, forms, spreadsheets, or documents) on our servers. Those remain on Google's servers. We only access this data to display it in the add-on and perform actions on your behalf. Choice Eliminator Live is the one exception, described below. Form Builder also keeps the text you give it for a limited time, described below. Slides Translator sends the text of your slides through our server to be translated and does not keep it, as also described below.

What we store:

  • Your email address (for account identification)
  • Your add-on settings and preferences
  • Your subscription status
  • A limited set of technical signals used to prevent abuse (described under Fraud and Abuse Prevention below)
  • For Choice Eliminator Live only: the hosted copy of your form and the responses submitted through it (described below)
  • For Form Builder only: a record of each build and, for a limited time, the text sent to the model and the questions it returned (described below)
  • For Slides Translator only: a record of each translation, without the text of your slides (described below)

We do not sell your data, and we share it only with the service providers needed to operate Skyfield (such as our hosting provider) or where required by law.

Hosted Forms (Choice Eliminator Live)

Choice Eliminator Live works by hosting your form, because holding a limit on each answer choice while many people submit at the same moment is not something Google Forms can do on its own. When you turn it on, the add-on sends that form's structure — its title, description, questions, and answer choices — to our servers, and we publish it at a Skyfield link you share with respondents.

Answers submitted through that link are stored on our servers, together with a count of how many people picked each choice. Answers submitted through your original Google Forms link never reach us, no other form in your Google account is read, and the add-on creates no files in your Drive.

You can ask us to delete a hosted form and its responses at any time — see Deleting Your Data below.

AI Processing (Form Builder)

Form Builder turns text into form questions. When you paste text or choose a file, the add-on sends that text, or the text of that file, to our server (skyfield.cloud). A scanned document or an image, such as a photo of a paper form, is sent as the file itself. Our server sends it to an AI language model, which reads the questions out of it. The model is run by a third-party AI provider acting on our behalf. A Google Form you choose to copy is read through Google's Forms API and is never sent to us.

For each build, our server records your email address, the model used, the number of questions, the size of the input, token counts and whether the build succeeded. Your monthly free allowance is counted from this record.

To check and improve the quality of Form Builder, we keep the text sent to the model and the questions it returned for a limited time, until our quality review is done, and then delete them. They may be reviewed automatically by AI service providers acting on our behalf. They are not used to train AI models and are not sold. The file itself is never stored, only the text read from it. When you send us feedback with a file, we keep that file and your note until we have looked at them, and then delete them. You can ask us to delete them by emailing info@skyfield.cloud.

AI Processing (Slides Translator)

Slides Translator translates Google Slides presentations. When you translate, the add-on sends the text of the slides you chose (text boxes, tables and speaker notes), the presentation's title and your glossary to our server (skyfield.cloud). Our server sends them to an AI language model, which translates the text, and returns the translation to the add-on. The model is run by a third-party AI provider acting on our behalf. The add-on writes the translation into your presentation, or into a copy of it in your Drive, through Google's Slides and Drive APIs, so your presentation stays on Google's servers.

We do not store the text of your slides, your glossary or the translations. For each translation, our server records your email address, the number of slides, the target language, whether the translation went into the presentation or into a copy, and the time. Your monthly free allowance is counted from this record. Your text is not used to train AI models and is not sold.

Your glossary and the last language you picked are saved in the presentation. Your recent languages, whether you translate into a copy and whether speaker notes are translated are saved in your Google account. Both stay on Google's servers.

Fraud and Abuse Prevention

To protect our add-ons from abuse — such as repeatedly creating new accounts to get unlimited free trials — we collect a small set of technical signals each time you open an add-on:

  • Your IP address, and the approximate country it indicates
  • Standard browser and device details (such as your browser, operating system, language, and time zone)
  • A device fingerprint: a short, one-way code computed from your browser and device details. It cannot be turned back into those details and does not identify you by name.

We use these signals to detect and prevent abuse of our add-ons. We do not use any of this to build advertising or marketing profiles or to track you across other websites, and we never sell it. We rely on our legitimate interest in preventing fraud to process this data, and you can object at any time by emailing info@skyfield.cloud.

Data Retention and Deletion

How Long We Keep Your Data

We retain your personal data (email address, add-on settings, subscription status) only as long as necessary to provide our services:

  • Active accounts: Data retained while you use our add-ons
  • Inactive accounts: Data may be deleted after 12 months of inactivity
  • Subscription records: Retained as required for billing/legal compliance
  • Abuse-prevention signals: Kept only as long as needed to detect and prevent abuse, then removed or anonymised
  • Text and questions from Form Builder: Kept for a limited time, until our quality review is done, then deleted
  • Slides Translator translation records: Kept with the rest of your account data, as described above. They never contain the text of your slides

We do not retain copies of your Google files (forms, spreadsheets, etc.) — these remain solely on Google's servers.

Deleting Your Data

You can request deletion of your data at any time by emailing info@skyfield.cloud. Upon receiving a verified request:

  • We will delete your stored data within 30 days
  • Uninstalling the add-on immediately revokes our access to your Google data
  • Some data may be retained if required by law or for fraud prevention

To fully remove the add-on's access to your Google account, visit your Google Account permissions and revoke access.

External Services

Our add-ons connect to our backend (skyfield.cloud) to:

  • Authenticate your account
  • Check your subscription tier
  • Process upgrades

All connections use HTTPS encryption.

Form Builder also uses third-party AI providers acting on our behalf. One reads the questions out of the text you give it, and others review the text and the questions for quality. See AI Processing above.

Slides Translator also uses a third-party AI provider acting on our behalf, which translates the text of your slides. See AI Processing above.
