Privacy Policy

Last updated: 14 September 2026

Who we are

Auto Short is a Windows app (a local engine plus an interface you use from your browser) developed and operated by José Ramón Ruiz Gil ("we", "us"), the data controller. Contact: autoshortmail@gmail.com.

The principle: your video never leaves your PC

Auto Short processes the video, audio, transcription and montage locally on your machine. No video or audio file is uploaded to our servers or to third parties. The only thing that leaves your machine for our service is text: the transcription, needed to plan the cuts, and for music edits the lyrics you paste plus descriptions of the shots.

What data we process and on what legal basis

• Transcription text (basis: performance of the contract): to plan the cuts, the app sends our service the clip's transcription as text. It is processed in memory and not stored on our systems. It may contain names or other personal data present in the audio; treat it with the same responsibility as your source material.
• Music edit: lyrics and shot descriptions (basis: performance of the contract): to pick a shot for each line, the app sends the lyrics text of the section you choose (the lyrics you paste), generic tags for the candidate shots (e.g. "city at night") and, when present, short snippets of what is said in those shots. Visual analysis runs on your machine with a local model: no frames, audio, paths or file names are ever sent, and the model does not identify people. It is processed in memory and not stored. The visual and silhouette models are downloaded once from GitHub without sending any of your data; the silhouette only separates people from the background to place words behind them.
• License key (basis: performance of the contract): sent with each request to verify your subscription is active and apply the monthly usage limit.
• Device identifier and IP address (basis: legitimate interest in preventing abuse): during the free trial we use an identifier generated on your machine and, transiently, your IP address to enforce the free quota and prevent fraud. We do not use them to profile you.
• Aggregated usage metrics (basis: legitimate interest): we count anonymous funnel events (downloads, trials started, paid calls) in aggregate figures, without identifying you personally.
• Payment and billing data (basis: performance of the contract and legal obligation): handled entirely by our merchant of record, Polar. We do not store card numbers or bank details. See Polar's privacy policy.
• Website analytics (basis: legitimate interest): this site uses Vercel Web Analytics, a cookieless analytics that collects aggregate visit data (page, country, device type) without identifying you individually or tracking you across sites.

Processors and providers

• Polar (payments, billing and license management).
• Anthropic (processing by the AI model of the transcription text and, for music edits, of the lyrics and shot descriptions; subject to its commercial terms, with no use for model training).
• Vercel (web service infrastructure and site analytics).
• Upstash (usage-limit and trial-quota counter tied to your license or device).
• GitHub (hosting of the installer and of the music edit's local models: shot analysis and people silhouettes; the app checks from your browser which version is the latest published one, at most once a day).

International transfers

Some of these providers are located outside the European Economic Area (e.g. in the USA). Where an international transfer occurs, it is carried out with the appropriate safeguards under the GDPR (such as the European Commission's Standard Contractual Clauses or an applicable adequacy framework).

What we do NOT do

• We do not sell or share your data with third parties for commercial purposes.
• We do not store your videos, audio, transcriptions or cut plans.
• We do not use tracking cookies or advertising on this website.

Retention

Transcriptions are processed and discarded immediately. Usage and trial counters are kept for the current cycle. Customer data (email, invoices) is kept by Polar per its policy and applicable tax law.

Your rights

You can exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to autoshortmail@gmail.com. If you reside in the EU, you may also lodge a complaint with your data protection authority (in Spain, the Spanish Data Protection Agency, aepd.es).

Minors

Auto Short is a professional product intended for adults. It is not directed at minors, and we do not knowingly collect their data.

Changes to this policy

If we change this policy, we will update the date on this page. Material changes will be communicated by email to active customers.
